摘　　要：滑坡是一种分布广泛、多发性的地质灾害,对人民生命财产和各项社会活动以及资源造成极大的损失,因此加强对滑坡稳定性和治理的研究是十分必要的。本文以西寺村滑坡为研究对象,在勘查钻探等资料的基础上,采用GEO5软件,运用毕肖普法对3-3′剖面进行稳定性计算,计算出天然、暴雨、地震3种工况下的稳定性系数,在利用MIDAS软件对滑坡的3种工况进行验算,并将计算结果进行对比分析,得出该滑坡在暴雨工况下处于不稳定状态,存在再次滑动失稳的可能。Landslide is a widespread,multiple geological hazard,which will cause great losses to people’s lives,property and social activities and resources. Therefore,it is necessary to strengthen the study of landslide stability and control. In this paper,Xi Si Cun landslide as the research object,on the basis of exploration drilling data,the GEO5 software is used to calculate the stability of the 3-3′proflie by using the Bishop method to calculate the stability under three conditions of natural,heavy rain and earthquake. The MIDAS software is used to check the three working conditions of the landslide,and the calculation results are compared and analyzed. It is concluded that the landslide is in an unstable state under heavy rain conditions,and there is the possibility of re-sliding instability.
