摘要
Abstract
Yujia landslide is located in Banxi Town,Yinjiang County,Guizhou Province.Since June 2017,due to continuous rainfall,the cracks of Yujia landslide have gradually widened and deepened,posing a threat to the life and property safety of 78 households below the landslide body.Based on detailed field investigations,this article analyzes the development characteristics of the Yujia landslide and conducts stability analysis of the landslide using FLAC3D numerical simulation.The results indicate that Yujia landslide is a translational soil landslide,and the main deformation zone of the landslide is the accumulation above the foundation cover interface,with the maximum value located in the middle of the slope.Therefore,it should pay attention to the penetration of landslide sliding surfaces and the resulting slope instability under the influence of triggering factors such as heavy rainfall and human engineering activities.关键词
