At 21.19 on 8 August 2017, an Ms 7.0 earthquake struck the Jiuzhaigou scenic spot in northwestern Sichuan Province, China. The is a strike-slip with focal depth of 20 km at 33.20° N and 103.82° E, was caused by two concealed faults. According to emergency investigations remote sensing interpretations, triggered 1780 landslides, damaged one dam (Nuorilang Waterfall) broke (Huohua Lake). landslides mainly occurred Rize Valley Shuzheng Jiuzhai Paradise. involved hanging wall back-slope effects,...
The Sichuan–Tibet railway (STR), beginning from Chengdu in Sichuan Province and ending Lhasa Tibet Autonomous Region, runs across the southeastern margin of Qinghai–Tibet Plateau (QTP). Due to intense tectonic activity, deeply incised valleys, high geostress frequent earthquakes, STR area is a typical large landslide-prone area. To gain insights into landslides along STR, an covering 3.34 × 105 km2 that extends 80–150 km on both sides was used examine spatial distribution corresponding...
On 1 June 2022, a magnitude Ms 6.1 (Mw 5.8) earthquake, named the 2022 Lushan struck southern segment of Longmenshan fault zone, with an epicenter at 30.395°N, 102.958°E and focal depth approximately 12.0 km. To gain insight into landslides triggered by this event characteristics coseismic in we collected multitemporal satellite images carried out field investigations. The results reveal that least 1288 over affected area 1470 km2. total landslide is 5.33 km2, highest concentration reaches...
A concentration of building damage and slope failure near the crest has been observed during numerous earthquakes. Documented researches have shown that combination topography geological structure (joint) significantly affects seismic response slope. To investigate this issue, a series numerical simulation analyses are performed for containing horizontal joints by varying normalized joint stiffness (K), ratio normal to shear (kn/ks), spacing, height, angle, loading frequency. The...
摘要: 川藏铁路建设面临脆弱地质环境的约束，沿线重大地质灾害的孕灾过程及成灾机理研究能为有效防灾提供技术支撑.基于详细的现场调查，揭示川藏铁路廊道泸定段发育3处大型滑坡及4条泥石流沟.区内大型滑坡的孕灾因素主要有以下3点: (1)康滇古隆起多期强烈东西向挤压，致使近南北向长大结构面发育且与河谷岸坡大致平行; (2)河谷走向与最大主应力方向垂直，谷坡岩体强烈卸荷; (3)鲜水河断裂活动产生震动作用，在三面临空的突出地形、坡折微地貌处地震波放大效应叠加背坡效应，导致地震波被放大3至6倍，使得顺坡向陡缓结构面控制的高位岩体发生大规模失稳，从而导致大型滑坡发生.区内构造破碎，且受强震震裂作用影响，支沟沟谷物源丰富，沟域形态利于汇水及物源启动，受汛期7~9月集中降雨影响，易激发群发性泥石流.泥石流活动影响施工营地安全，边坡地震动放大效应影响桥位区仰坡岩体稳定性. 关键词: 川藏铁路 / 泸定 地质灾害 孕灾过程 形成机制 工程地质
