| 1 | Test Investigation on Liquefied Deformation Structure in Saturated Lime-Mud Composites Triggered by Strong Earthquakes显示文摘Three identical model boxes were made from transparent plexiglass and angle iron. Using the method of sinking water and according to the sedimentary rhythm of saturated calcium carbonate(lime-mud) intercalated with cohesive soil,calcites with particle sizes diameters of ≤ 5 μm,10–15 μm and 23–30 μm as well as cohesive soil were sunk alternatively in water of three boxes to build three test models,each of which has a specific size of calcite. Pore water pressure gauges were buried in lime-mud layers at different depths in each model,and connected with a computer system to collect pore water pressures. By means of soil tests,physical property parameters and plasticity indices(Ip) were obtained for various grain-sized saturated lime-muds. The lime-muds with Ip ranging from 6.3 to 8.5(lower than 10) are similar to liquid saturated silt in the physical nature,indicating that saturated silt can be liquefied once induced by a strong earthquake. One model cart was pushed quickly along the length direction of the model so that its rigid wheels collided violently with the stone stair,thus generating an artificial earthquake with seismic wave magnitude greater than VI degree. When unidirectional cyclic seismic load of horizontal compression-tension-shear was imposed on the soil layers in the model,enough great pore water pressure has been accumulated within pores of lime-mud,resulting in liquefaction of lime-mud layers. Meanwhile,micro-fractures formed in each soil layer provided channels for liquefaction dewatering,resulting in formation of macroscopic liquefaction deformation,such as liquefied lime-mud volcanoes,liquefied diapir structures,vein-like liquefied structures and liquefied curls,etc. Splendid liquefied lime-mud eruption lasted for two to three hours,which is similar to the sand volcano eruption induced by strong earthquake. However,under the same artificial seismic conditions,development of macroscopic liquefied structures in three experimental models varied in shape,depth and quantity,indicating that excess pore water pressure ratios at initial liquefaction stage and complete liquefaction varied with depth. With size increasing of calcite particle in lime-mud,liquefied depth and deformation extent increase accordingly. The simulation test verifies for the first time that strong earthquakes may cause violent liquefaction of saturated lime-mud composed of micron-size calcite particles,uncovering the puzzled issue whether seafloor lime-mud can be liquefied under strong earthquake. This study not only provides the latest simulation data for explaining the earthquake-induced liquefied deformations of saturated lime-mud and seismic sedimentary events,but also is of great significance for analysis of foundation stability in marine engineering built on the soft calcium carbonate layers in neritic environment. | TIAN Hongshui ZHANG Shenhe ZHANG Aishe | 2016 | Acta Geologica Sinica(English Edition)2016，90，6： | 9 |
| 2 | Neogene Paleoseismic Events and the Shanwang Biota's Burial in the Linqu Area,Shandong Province,China显示文摘Several paleoseismic events are recorded in the Neogene Linqu Group, exposed in the Linqu area, Shandong Province, China. The events were interpreted on the basis of fieldwork and laboratory analysis, which showed the presence of seismites with plastically deformed soft-sediment deformation structures in the Shanwang Formation, and of seismic volcanic rocks in the Yaoshan Formation which show brittle deformation. The earthquake-triggered soft-sediment deformations in the seismites include load structures, ball-and-pillow structures, flame structures, pillow-like beds, boudinage structures, slump folds, syn-depositional faults, veins of liquefied sand, and dikes of liquefied sandy lime-mud. The seismic activity is also reflected in what might be called ‘brittle seismites'; these originated when, under the influence of seismic vibrations, semi-consolidated conglomerate was shattered. Moreover, volcanic activity is related to intense earthquakes that affected basalts intercalated with sand layers; these successions are known as ‘seismic volcanic rocks', which are characterized by veins of liquefied sand intruding the basalts. All above traces of paleoseismic activity were left from one single time span of 4 Ma with active seismicity that took place 14–10 Ma. This time span is known as ‘the Linqu Neogene Paleoseismic Active Period', which is divided into four paleoseismic episodes, which were responses to tectonic extension and basin rifting in this area. It even includes the activity of the Yishu Fault Zone during the Miocene and the Neogene. The ratios of trace elements in the seismites, w(La)/w(Sc) and w(La)/w(Th) are higher than the average value of the upper crust, but w(Th)/w(Sc) is lower; this is geochemical evidence for the basin rifting that resulted in a high sedimentation rate. The intense and frequent paleo-earthquakes are held responsible for the rapid burial of the Shanwang Biota. Secondary earthquake-induced processes(e.g. slumping of a lake shore and the strongly increased lacustrine sedimentation rate) contributed to the rapid burial of the biota. | TIAN Hongshui A.J.(Tom) VAN LOON ZHANG Zengqi ZHANG Shenhe ZHANG Banghua Lü Mingying LI Fuchang MA Xuemin | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 7 |
| 3 | Optical superoscillatory waves without side lobes along a symmetric cut显示文摘Optical superoscillation refers to an intriguing phenomenon of a wave packet that can oscillate locally faster than its highest Fourier component,which potentially produces an extremely localized wave in the far field.It provides an alternative way to overcome the diffraction limit,hence improving the resolution of an optical microscopy system.However,the optical superoscillatory waves are inevitably accompanied by strong side lobes,which limits their fields of view and,hence,potential applications.Here,we report both experimentally and theoretically a new superoscillatory wave form,which not only produces significant feature size down to deep subwavelength,but also completely eliminates side lobes in a particular dimension.We demonstrate a new mechanism for achieving such a wave form based on a pair of moonlike sharp-edge apertures.The resultant superoscillatory wave exhibits Bessel-like forms,hence allowing long-distance propagation of subwavelength structures.The result facilitates the study of optical superoscillation and on a fundamental level eliminates the compromise between the superoscillatory feature size and the field of view. | Yanwen Hu Shiwang Wang Junhui Jia Shenhe Fu Hao Yin Zhen Li Zhenqiang Chen | 2021 | Advanced Photonics2021，3，4： | 3 |

| 19 | Optimized weak measurement of orbital angular momentum-induced beam shifts in optical reflection显示文摘Tiny but universal beam shifts occur when a polarized light beam is reflected upon a planar interface.Although the beam shifts of Gaussian beams have been measured by the weak measurement technique, the weak measurement for orbital angular momentum(OAM)-induced spatial shifts of vortex beams is still missing.Here, by elaborately choosing the preselection and postselection states, the tiny OAM-induced Goos–H?nchen and Imbert–Fedorov shifts are amplified at an air–prism interface. The maximum shifts along directions both parallel and perpendicular to the incident plane are theoretically predicted and experimentally verified with optimal preselection and postselection states. These maximum shifts can be used to determine the OAM of vortex beams. | Wenjin Long Jintao Pan Xinyi Guo Xiaohe Liu Haolin Lin Huadan Zheng Jianhui Yu Heyuan Guan Huihui Lu Yongchun Zhong Shenhe Fu Li Zhang Wenguo Zhu Zhe Chen | 2019 | Photonics Research2019，7，11： | 1 |
