布沼坝露天矿西帮变形滑坡成因与稳定性分析
Causes of deformation landslide and stability analysis of western slope in Buzhaoba Open-pit Mine
摘要
Abstract
In order to reveal the causes of deformation landslides on the western slope of Buzhangba Open-pit Mine and achieve the accurate evaluation of slope stability,the article systematically analyzes the influence of factors such as formation lithology,rock mass structure,water,and engineering disturbance on the western slope.The article uses FLAC3D and strength reduction methods to perform numerical modeling and stability analysis on four typical sections in the deformation zone of western slope landslide.The results show that the long-term infiltration of groundwater into weak layers of the slope and mining engineering disturbance are the main causes of the landslide.The stability coefficients of the 334 and 340 profiles obtained from numerical simulation are 1.230 and 1.176,respectively,indicating a stable state.The stability factors of sections 336 and 338 are 1.066 and 1.082,respectively,indicating that these two sections are under-stable.The analysis results are consistent with the actual development state of the western slope landslide.关键词
