摘　　要：以牛犊山西侧滑坡为研究对象,对滑坡区域及周边进行地质勘测,调查滑坡地层岩性、水文地质条件、工程地质条件、物理力学参数,利用原理为极限平衡法的slide软件对滑坡采用瑞典条分法进行稳定性计算,采用简布法和毕肖普法进行稳定性校核,计算结果表明:在自重工况下,牛犊山正中假日酒店西侧边坡坡体处于基本稳定~稳定状态;在自重和暴雨工况下,坡体处于基本稳定~不稳定状态,边坡岩土体蠕滑变形持续发展到一定程度后,坡体有可能进一步发生滑动破坏,需要对滑坡采取进一步的支护处理措施。With calf mountain landslide as the research object,the west side of the landslide area and the surrounding geological survey,survey landslide stratigraphic lithology,hydrogeological condition,engineering geological conditions,physical and mechanical parameters,using the principle of limit balance method of slide software calculating the stability of landslide with Swedish article points method,Jane cloth method and the Bishop method is adopted to improve the stability,the calculation results show that:under the working condition of gravity,the calf mountain in the middle of the holiday inn on the west side slope body in basic stability to a stable state,under dead weight and heavy rain conditions,the slope is basically stable to unstable.After the creep deformation of the rock and soil mass of the slope continues to develop to a certain extent,the slope is likely to slide further,so it is necessary to take further support treatment measures for the landslide.
