摘　　要：针对北盘江万家口子水电站左坝肩的抗滑稳定影响大坝的整体稳定与安全问题,基于块体理论,在分析工程地质条件基础上,构建了左坝肩边坡地质模型,利用赤平投影法搜索关键块体,采用SLOPE3D软件确定左坝肩边坡块体的几何特征及不同工况下的抗滑稳定性,并提出了加固设计方案,取得了较好的效果,可供同类工程借鉴。Anti-sliding stability of left abutment of Wanjiakouzi hydropower station in Beipanjiang basin has impact on the dam stabilization and safety.Based on the analysis of engineering geologic condition,slope geologic model of left abutment is established by using block theory.The stereographic projection method is used to find the key mass.And then the geometric characteristic of slope block and anti-sliding stability under the different conditions for left abutment are obtained by using SLOPE3D software.Finally,the scheme of reinforcing design is proposed.It has good effect and provides reference for similar engineering project.
