摘　　要：简单介绍了ZK51＋260~ZK51＋390左侧滑坡的工程地质概况,结合滑坡的实际变形情况,分析了滑坡的成因机制,采用瑞典条分法对其稳定性进行了分析与评价。滑坡在饱水工况下、自重＋地震工况下处于不稳定状态。根据计算结果提出了具体的处治措施。The geological conditions for the landslide on the left side from ZK51 ＋260 to ZK51 ＋390 is briefly introduced, and combining with the actual landslide deformation, the causes and mechanism of landslides are analyzed. The Sweden slice method is used to analyze and evaluate the stability. Landslides in saturated conditions, weight plus seismic conditions keep in an unstable state. According to calculation results specific treatment measures are proposed.
