1基于冻融次数-物理时间比拟理论的冻土长期强度预测方法显示文摘冻融作用可以改变土的结构,引起其力学特征的变化,从而影响到冻土工程的稳定性。由于冻融周期的设定不尽相同,因此大量的试验结果不能有效地进行对比分析。另外,对于冻融作用下土体力学特征的预测也成为研究的难点。在冻土遗传蠕变理论的基础上,利用球型模板压入仪作为测试方法,提出了一种冻融次数-物理时间比拟的方法。把冻融周期(次数)转化成物理时间(min),将不同冻融周期土的长期强度曲线簇映射到同一坐标中,利用该归一化曲线进行长期抗剪强度的预测,并选取了两种土样进行了测试,分别得到了相关的长期抗剪强度的预测方程。该方法对冻融作用下土体力学行为的成果对比研究以及长期强度的预测有重要的理论意义,对寒区工程稳定性预测分析也具有工程实践价值。张泽 马巍 ROMAN Lidia MELNIKOV Andrey 杨希 李宏璧 2021岩土力学2021,42,1:6
2冻融作用下砂土颗粒形态变化规律研究显示文摘土壤中的石英颗粒的表面形态不仅是该沉积物物源区沉积环境、搬运机制的信息载体,同时也会直接影响到砂土的宏观物理特性,对力学和实际工程有着重要的意义。借助显微与高精度图像处理技术,采用长径比,磨圆度两个量化指标,对经过不同次数冻融作用的两组砂土颗粒进行观察。结果表明:砂土颗粒在冻融循环过程中,由于颗粒之间的相互作用,磨圆度先增大后减小,最后趋于稳定;长径比先减小,后增加,最后趋于稳定。长径比与磨圆度的变化曲线共轭。恽晴飞 张泽 明姣 付翔宇 周成林 Andrey MELNIKOV 2020冰川冻土2020,42,1:5
3应用浅表静脉引流腹壁下动脉穿支皮瓣(DIEP)乳房再造术显示文摘目的总结应用浅表静脉引流腹壁下动脉穿支皮瓣(DIEP)乳房再造术的手术方法,探讨分析其适应证及优点。方法精细解剖浅表腹部静脉系统,并游离腹部浅表静脉及腹壁下动、静脉穿支,形成带有浅表静脉的腹壁下动脉穿支蒂皮瓣,将腹壁下动、静脉与患者胸廓内血管相吻合,浅表静脉与胸骨旁穿支血管静脉相吻合,进行乳房再造。结果自2016年起莫斯科国立谢东诺夫第一医科大学第一附属医院整形与重建外科此种术式临床应用35例,所有皮瓣全部存活,再造乳房外形满意。结论应用浅静脉吻合胸骨旁穿支血管静脉引流,可有效防止皮瓣灌注不足及静脉危象造成的危险并发症,使皮瓣成活率提高,达到手术最终目的。陈阔 Reshetov I.

4Dissociation behavior of “dry water” C_3H_8 hydrate below ice point:Effect of phase state of unreacted residual water on a mechanism of gas hydrates dissociation显示文摘The results on a dissociation behavior of propane hydrates prepared from 'dry water' and contained unreacted residual water in the form of ice inclusions or supercooled liquid water(water solution of gas) were presented for temperatures below 273 K.The temperature ramping or pressure release method was used for the dissociation of propane hydrate samples.It was found that the mechanism of gas hydrate dissociation at temperatures below 273 K depended on the phase state of unreacted water in the hydrate sample.Gas hydrates dissociated into ice and gas if the ice inclusions were in the hydrate sample.The samples of propane hydrates with inclusions of unreacted supercooled water only(without ice inclusions) dissociated into supercooled water and gas below the pressure of the supercooled water-hydrate-gas metastable equilibrium.Andrey O Drachuk Vladimir P Melnikov Nadezhda S Molokitina Anatoliy N Nesterov Lev S Podenko Aleksey M Reshetnikov Andrey Yu Manakov 2015Journal of Energy Chemistry2015,24,3:2
5Phenomena caused by seismic and geocryological processes across linear infrastructure, South Yakutia, Russia显示文摘High seismic activity, difficult permafrost and hydrogeological conditions of South Yakutia(Russia) complicate building and exploitation of engineering construction and require additional detailed and complex research. These conditions are evident within two sites. The first site is located in the middle reach of the Duray River, where it is crossed by the highway Lena. The second site is located on the right side of the Chulmakan River Valley, 400 meters to the east of the ESPO oil pipeline route. Seismic events, occurring four years ago, led to landslides in the mentioned sites. Formation of joint fissures on slopes assisted drainage of aquifers of free water exchange zone. It is worth noting that at the Duray River site, 59 cm of active soil slumping movement towards the roadbed has occurred within two summer months. Such a process is complicated by cryogenic disintegration of rocks in the base of the landslide body due to groundwater discharge and icing formation in winter.L. Gagarin A. Melnikov V. Ogonerov I.
