摘　　要：本文从基本地质条件人手，对贵州某水库大坝左岸边坡的稳定性进行分析，并根据地质结构特征，选择了楔形滑动和平面滑动两种模式分别进行计算。其计算参数的选择，主要依据边坡开挖过程中发生的边坡滑塌资料进行反演取得。经过三种工程处理方案（锚固、锚固＋局部开挖、开挖＋局部锚固）的经济技术综合对比，将锚固＋局部开挖作为推荐方案。该水库大坝左岸边坡经过局部开挖和锚索加固之后，一直处于稳定状态，工程处理效果较好。the slope stability of the left bank of a reservoir Dam in Guizhou Province is analyzed based on the basic geological conditions in the article, and according to the geological structure characteristics, two modes, the slide wedge and plane sliding, are selected respectively to calculate. The selection of the calculation parameters is mainly basic on the inversion of the slope sliding data obtained during slope excavation process. After economic and technological contrast of three engineering treatment schemes （anchor, anchor ＋ partial excavation, excavation ＋ local anchor）, anchor ＋ local anchor scheme is recommended. After partial excavation and anchor cable reinforcement, the left bank slope of the reservoir dam has been in a stable state, so the treatment effect is good.
