| 1 | Protection against water or mud inrush in tunnels by grouting:A review显示文摘Grouting is a major method used to prevent water and mud inrush in tunnels and underground engineering.In this paper,the current situation of control and prevention of water and mud inrush is summarized and recent advances in relevant theories,grout/equipment,and critical techniques are introduced.The time-variant equations of grout viscosity at different volumetric ratios were obtained based on the constitutive relation of typical fast curing grouts.A large-scale dynamic grouting model testing system(4000 mm × 2000 mm × 5 mm) was developed,and the diffusions of cement and fast curing grouts in dynamic water grouting were investigated.The results reveal that the diffusions of cement grouts and fast curing grouts are U-shaped and asymmetric elliptical,respectively.A multiparameter real-time monitoring system(φ = 1.5 m,h = 1.2 m) was developed for the grouting process to study the diffusion and reinforcement mechanism of grouting in water-rich faulted zone.A high early strength cream-type reinforcing/plugging grout,a high permeability nano-scale silica gel grout,and a high-expansion filling grout were proposed for the control of water hazards in weak water-rich faulted zone rocks,water inrush in karst passages,and micro-crack water inrush,respectively.Complement technologies and equipment for industrial applications were also proposed.Additionally,a novel full-life periodic dynamic water grouting with the critical grouting borehole as the core was proposed.The key techniques for the control of water inrush in water-rich faulted zone,jointed fissures and karst passages,and micro-crack water inrush were developed. | Shucai Li Rentai Liu Qingsong Zhang Xiao Zhang | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，5： | 27 |
| 2 | Predicting geological hazards during tunnel construction显示文摘The complicated geological conditions and geological hazards are challenging problems during tunnel construction,which will cause great losses of life and property.Therefore,reliable prediction of geological defective features,such as faults,karst caves and groundwater,has important practical significances and theoretical values.In this paper,we presented the criteria for detecting typical geological anomalies using the tunnel seismic prediction(TSP) method.The ground penetrating radar(GPR) signal response to water-bearing structures was used for theoretical derivations.And the 3D tomography of the transient electromagnetic method(TEM) was used to develop an equivalent conductance method.Based on the improvement of a single prediction technique,we developed a technical system for reliable prediction of geological defective features by analyzing the advantages and disadvantages of all prediction methods.The procedure of the application of this system was introduced in detail.For prediction,the selection of prediction methods is an important and challenging work.The analytic hierarchy process(AHP) was developed for prediction optimization.We applied the newly developed prediction system to several important projects in China,including Hurongxi highway,Jinping II hydropower station,and Kiaochow Bay subsea tunnel.The case studies show that the geological defective features can be successfully detected with good precision and efficiency,and the prediction system is proved to be an effective means to minimize the risks of geological hazards during tunnel construction. | Shucai Li Shuchen Li Qingsong Zhang Yiguo Xue Bin Liu Maoxin Su Zhechao Wang Shugang Wang | 2010 | Journal of Rock Mechanics and Geotechnical Engineering2010，2，3： | 25 |
| 3 | Characterizations and mechanical properties of impregnated diamond segment using Cu-Fe-Co metal matrix显示文摘Diamond impregnated Cu-Fe-Co based saw-blade segments are directly processed by vacuum and pressure-assisted sintering at different temperature,with the purpose of reducing the cobalt content in diamond tools.Copper and iron are used as the bonding elements and co-balt-chrome pre-alloyed powder is used as the hardening phase.Effects of sintering temperature on microstructures and mechanical properties of the sintered matrix and diamond graphitization were investigated by X-ray diffraction analysis,electron probe micro-analyzer,universal testing machine,digital Rockwell hardness tester and Raman scattering analyzer.Results showed that microstructures of the sintered matrix were refined and porosities in the sintered matrix were closed to a more spherical-like shape with the increase of the sintering temperature.Densification,hardness and tensile strength of the matrix sintered at 820 ℃ were 12.75%,2.72% and 156.38% higher than that of the matrix sintered at 740 ℃,respectively.Diamond graphitization was not occurred at 820 ℃.The hardness and the tensile strength rose 32.8% and 13.5%,respectively,after 7.5 h ageing treatment.The matrix densification ascent and the dispersed distribution of Co-Cr pre-alloyed powders contributed a hardness improvement and a tensile strength improvement to the Cu-Fe based matrix. | Li, Wensheng Zhang, Jie Wang, Shucai Dong, Hongfeng Li, Yaming Liu, Yi | 2012 | Rare Metals2012，31，1： | 19 |

| 5 | Detecting and monitoring of water inrush in tunnels and coal mines using direct current resistivity method:A review显示文摘Detecting, real-time monitoring and early warning of underground water-bearing structures are critically important issues in prevention and mitigation of water inrush hazards in underground engineering.Direct current(DC) resistivity method is a widely used method for routine detection, advanced detection and real-time monitoring of water-bearing structures, due to its high sensitivity to groundwater. In this study, the DC resistivity method applied to underground engineering is reviewed and discussed,including the observation mode, multiple inversions, and real-time monitoring. It is shown that a priori information constrained inversion is desirable to reduce the non-uniqueness of inversion, with which the accuracy of detection can be significantly improved. The focused resistivity method is prospective for advanced detection; with this method, the flanking interference can be reduced and the detection distance is increased subsequently. The time-lapse resistivity inversion method is suitable for the regions with continuous conductivity changes, and it can be used to monitor water inrush in those regions. Based on above-mentioned features of various methods in terms of benefits and limitations, we propose a three-dimensional(3D) induced polarization method characterized with multi-electrode array, and introduce it into tunnels and mines combining with real-time monitoring with time-lapse inversion and cross-hole resistivity method. At last, the prospective applications of DC resistivity method are discussed as follows:(1) available advanced detection technology and instrument in tunnel excavated by tunnel boring machine(TBM),(2) high-resolution detection method in holes,(3) four-dimensional(4D)monitoring technology for water inrush sources, and(4) estimation of water volume in water-bearing structures. | Shucai Li Bin Liu Lichao Nie Zhengyu Liu Mingzhen Tian Shirui Wang Maoxin Su Qian Guo | 2015 | Journal of Rock Mechanics and Geotechnical Engineering2015，7，4： | 12 |
| 6 | Influence of N on precipitation behavior,associated corrosion and mechanical properties of super austenitic stainless steel S32654显示文摘The influence of N on the precipitation behavior,associated corrosion,and mechanical properties of S32654 were investigated by microstructural,electrochemical,and mechanical analyses.Increasing the N content results in several alterations:(1) grain refinement,which promotes intergranular precipitation;(2) a linear increase in the driving force for Cr2 N and Mo activity,which accelerates the precipitation of intergranular Cr2 N and π phase,respectively;(3) a linear decrease in the driving force for σ phase and Cr activity,which suppresses the formation of intragranular σ phase.The total amount of precipitates first decreased and then increased with the N content increasing.Furthermore,the intergranular corrosion susceptibility depended substantially on the total amount of precipitates and also first exhibited a decreasing and then an increasing trend as the N content increased.In addition,aging precipitation caused a considerable decrement in the ultimate tensile strength(UTS) and a remarkable increment in the yield strength(YS).Both the UTS and YS always increased with N content increasing throughout the solution and aging process.Whereas the elongation was considerably sensitive to the aging treatment,it exhibited marginal variation with the N content increasing. | Shucai Zhang Huabing Li Zhouhua Jiang Zhixing Li Jingxi Wu Binbin Zhang Fei Duan Hao Feng Hongchun Zhu | 2020 | Journal of Materials Science & Technology2020，42，7： | 10 |

| 8 | New hypothesis and treatment targets of depression:an integrated view of key findings显示文摘Major depressive disorder(MDD) is a common and devastating psychiatric disorder characterized by persistent low mood,cognitive disorder,and impaired social function. Despite its complex mechanisms,increasing evidence has identified the involvement of neurotrophic factors,inflammatory cytokines,the hypothalamuspituitary-adrenal axis,and glutamate receptors in the pathophysiology of this illness. The present review synthesizes recent research achievements to defi ne the network between different hypotheses of MDD and to understand which part is most pivotal for its pathogenesis. By integrating MDD-related signal pathways,we highlight brain-derived neurotrophic factor(BDNF) dysfunction and increased apoptosis as the fi nal common cascades,and new therapeutic strategies aiming to enhance BDNF function have been shown to exert a rapid and effective antidepressant action. | Shangli Cai Shucai Huang Wei Hao | 2015 | Neuroscience Bulletin2015，31，1： | 9 |
| 9 | Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC. | Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun | 2022 | Cancer Communications2022，42，12： | 8 |
| 10 | Detrital Zircon U-Pb Geochronology from Greywackes in the Niujuanzi Ophiolitic Mélange, Beishan Area, NW China: Provenance and Tectonic Implications显示文摘The Niujuanzi ophiolitic mélange represents the remnant of oceanic crust between the Dunhuang massif and Mingshui-Hanshan massif. Greywacke from different tectonic slices in the Niujuanzi ophiolitic mélange were analyzed for detrital zircon U-Pb geochronology, trace elements and whole-rock trace elements to infer their provenance and the evolution of the Niujuanzi Ocean. Sample N-76 s containing Carboniferous spores has the youngest zircon age of 323 Ma, while sample N-85 s without fossils has the youngest zircon age of 449 Ma. The two samples were deposited no earlier than 323 and 449 Ma, respectively. The greywackes are depleted in large ion lithophile elements, and are relatively enriched in high field strength elements. The age spectra and trace element concentrations indicate that the sediments may have been deposited near the trench. The Hf, U, and Yb contents of zircons from sample N-76 s vary widely, whereas those from sample N-85 s have a narrow range. Sample N-76 s contains both continental and oceanic zircons, while sample N-85 s contains only continental zircons. The sediments were derived from the continental arc and accretionary wedge. The Paleozoic oceanic crust zircons have ages of 430–500 Ma, indicating the timing of the expansion of the HongliuheNiujuanzi-Xichangjing Ocean expansion. The oldest Paleozoic continental zircon has an age of 470 Ma, suggesting that the northward subduction of the oceanic crust may have started at that time. | Shengdong Wang Kexin Zhang Bowen Song Shucai Li Jianxing Li Jiyuan Yu Jianjun Bu | 2018 | Journal of Earth Science2018，29，1： | 8 |
| 11 | Effect of nitrogen on corrosion behaviour of a novel high nitrogen medium-entropy alloy CrCoNiN manufactured by pressurized metallurgy显示文摘A novel high nitrogen medium-entropy alloy CrCoNiN, which had higher strength and slightly lower ductility than CrCoNi alloy, was successfully manufactured by pressurized metallurgy. The microstructure and corrosion behaviour were investigated by microscopic, electrochemical and spectroscopic methods.The results indicated that nitrogen existed in the form of Cr_2N precipitates and uniformly distributed N atoms, and nitrogen alloying significantly refined the grain size. Besides, nitrogen enriched on the outmost surface of passive film and metal/film interface as ammonia(NH-_3 and NH_4^+) and CrN, respectively. The significant improvement of corrosion resistance of CrCoNiN was attributed to the lower metastable pitting susceptibility together with thicker, less defective and more compact passive film. | Hao Feng Huabing Li Xiaolei Wu Zhouhua Jiang Si Zhao Tao Zhang Dake Xu Shucai Zhang Hongchun Zhu Binbin Zhang Muxin Yang | 2018 | Journal of Materials Science & Technology2018，34，10： | 8 |
| 12 | Comparative study of model tests on automatically formed roadway and gob-side entry driving in deep coal mines显示文摘Automatically formed roadway(AFR)by roof cutting with bolt grouting(RCBG)is a new deep coal mining technology.By using this technology,the broken roadway roof is strengthened,and roof cutting is applied to cut off stress transfer between the roadway and gob to ensure the collapse of the overlying strata.The roadway is automatically formed owing to the broken expansion characteristics of the collapsed strata and mining pressure.Taking the Suncun Coal Mine as the engineering background,the control effect of this new technology on roadways was studied.To compare the law of stress evolution and the surrounding rock control mechanisms between AFR and traditional gob-side entry driving,a comparative study of geomechanical model tests on the above methods was carried out.The results showed that the new technology of AFR by RCBG effectively reduced the stress concentration of the roadway compared with gob-side entry driving.The side abutment pressure peak of the solid coal side was reduced by 24.3%,which showed an obvious pressure-releasing effect.Moreover,the position of the side abutment pressure peak was far from the solid coal side,making it more beneficial for roadway stability.The deformation of AFR surrounding rock was also smaller than the deformation of the gob-side entry driving by the overload test.The former was more beneficial for roadway stability than the latter under higher stress conditions.Field application tests showed that the new technology can effectively control roadway deformation.Moreover,the technology reduced roadway excavation and avoided resource waste caused by reserved coal pillars. | Qi Wang Manchao He Shucai Li Zhenhua Jiang Yue Wang Qian Qin Bei Jiang | 2021 | International Journal of Mining Science and Technology2021，31，4： | 8 |

| 14 | Optimality Analysis of Sensor-Target Geometries for Bearing-Only Passive Localization in Three Dimensional Space显示文摘Optimality analysis of sensor to target observation geometry for bearing-only passive localization is of practical significance in engineering and military applications and this paper generalized predecessors' researches in two-dimensions into three dimensional space. Based on the principles of Cramer-Rao lower bound(CRLB), Fisher information matrix(FIM) and the determinant of FIM derived by Cauchy-Binet formula, this paper configured the optimal observation geometry resulted from maximizing the determinant of FIM. Optimal observation geometry theorems and corresponding propositions were proved for N ≥ 2 sensors in three dimensions. One conjecture was proposed, i.e., when each range of N(N ≥ 4) sensors to the single target is identical, configuring the optimal geometry is equivalent to distributing N points uniformly on a unit sphere, which is one of the worldwide difficult problem. Studies in this paper can provide helpful reference for passive sensor deployment, route planning of detection platform and so on. | ZHONG Yu WU Xiaoyan HUANG Shucai LI Chengjing WU Jianfeng | 2016 | Chinese Journal of Electronics2016，25，2： | 6 |
| 15 | Application of GA-SVM in classification of surrounding rock based on model reliability examination显示文摘In order to improve the discrimination precision of support vector machine(SVM) in classification of surrounding rock, a Genetic Algorithm(GA) was used to optimize SVM parameters in the solution space.The idea of examination of model reliability was introduced to check the reliability of the SVM parameters,obtained by genetic algorithms.In the process of model reliability,a trend examination method is presented,which checks the reliability of the model via the influence trend of impact factors on the object of evaluation and their evaluation level.Trend examination methods are universal,showing new ideas in model reliability examination and can be used in any problems of examination of reliability of models,based on previous experience.We established a GA-SVM based reliability model of a classification the surrounding rock and applied it to a practical engineering situation.The result shows that the improved SVM has a high capability for generalization and prediction accuracy in classification of surrounding rock. | QIU Daohong LI Shucai ZHANG Lewen XUE Yiguo | 2010 | Mining Science and Technology2010，20，3： | 6 |
| 16 | Application of the expanded distinct element method for the study of crack growth in rock-like materials under uniaxial compression显示文摘The expanded distinct element method(EDEM)was used to investigate the crack growth in rock-like materials under uniaxial compression.The tensile-shear failure criterion and the Griffith failure criterion were implanted into the EDEM to determine the initiation and propagation of pre-existing cracks,respectively.Uniaxial compression experiments were also performed with the artificial rock-like samples to verify the validity of the EDEM.Simulation results indicated that the EDEM model with the tensile-shear failure criterion has strong capabilities for modeling the growth of pre-existing cracks,and model results have strong agreement with the failure and mechanical properties of experimental samples.The EDEM model with the Griffith failure criterion can only simulate the splitting failure of samples due to tensile stresses and is incapable of providing a comprehensive interpretation for the overall failure of rock masses.Research results demonstrated that sample failure primarily resulted from the growth of single cracks(in the form of tensile wing cracks and shear secondary cracks)and the coalescence of two cracks due to the growth of wing cracks in the rock bridge zone.Additionally,the inclination angle of the pre-existing crack clearly influences the final failure pattern of the samples. | Lei YANG Yujing JIANG Bo LI Shucai LI Yang GAO | 2012 | Frontiers of Structural and Civil Engineering2012，6，2： | 5 |
| 17 | Quantitatively assessing the pre-grouting effect on the stability of tunnels excavated in fault zones with discontinuity layout optimization:A case study显示文摘Pre?grouting is a popular ground treatment strategy utilized to enhance the strength and stability of strata during the excavation of a tunnel through a fault zone.Two important questions need to be answered during such an excavation.First,how should the grouting size be determined?Second,when should excavation begin after grouting?These two questions are conventionally addressed through empirical experience and standard criteria because a reliable quantitative approach,which would be preferable,has not yet been developed.To address these questions,we apply a recently proposed numerical approach known as discontinuity layout optimization,an efficient node-based upper bound limit analysis method.A case study is provided utilizing a tunnel located in a stratum characterized by complicated geological conditions,including soft soil and a fault zone.The factor of safety is used to quantitatively assess the stability of the tunnel section.The influences of the grouted zone thickness and the time-dependent material properties of the grouted zone on the stability of the tunnel section are evaluated,thereby assisting designers by quantitatively assessing the effects of pre-grouting. | Xiao YAN Zizheng SUN Shucai LI Rentai LIU Qingsong ZHANG Yiming ZHANG | 2019 | Frontiers of Structural and Civil Engineering2019，13，6： | 5 |

| 20 | Dissolution of different zinc salts and Zn uptake by Sedum alfredii and maize in mono-and co-cropping under hydroponic culture显示文摘Previous soil pot and field experiments demonstrated that co-cropping the hyperaccumulator Sedum alfredii with maize increased Zn phytoextraction by S. alfredii and decreased Zn uptake by maize shoots. This hydroponic experiment was conducted to investigate whether the facilitation of Zn phytoextraction by S. alfredii resulted from improved dissolution in this co-cropping system and its relation to root exudates. S. alfredii and maize were mono-and co-cropped (without a root barrier) in nutrient solution spiked with four Zn compounds, ZnS, ZnO, Zn3(PO4)2 and 5ZnO·2CO3·4H2O (represented as ZnCO3 ) at 1000 mg/L Zn for 15 days without renewal of nutrient solution after pre-culture. The root exudates were collected under incomplete sterilization and analyzed. The results indicated that the difference in Zn salts had a greater influence on the Zn concentration in maize than for S. alfredii, varying from 210-2603 mg/kg for maize shoots and 6445-12476 mg/kg for S. alfredii in the same order: ZnCO3 > ZnO >Zn3(PO4)2 > ZnS. For the four kinds of Zn sources in this experiment, co-cropping with maize did not improve Zn phytoextraction by S. alfredii. In most cases, compared to co-cropped and mono-cropped maize, mono-cropped S. alfredii resulted in the highest Zn2+ concentration in the remaining nutrient solution, and also had a higher total concentration of low molecular weight organic acids (LMWOA) and lower pH of root exudation. Root exudates did partly influence Zn hyperaccumulation in S. alfredii. | Cheng'ai Jiang Qitang Wu Shucai Zeng Xian Chen Zebin Wei Xinxian Long | 2013 | Journal of Environmental Sciences2013，25，9： | 3 |
