摘　　要：本文以三峡库区晒网坝滑坡为研究对象,根据滑坡地质条件和特征,结合滑坡稳定性的影响因素,选取三种工况:①工况一:天然状态(自重)+现状水位(135m);②工况二:天然状态+175m库水水位;③工况三:天然状态+175m库水水位+十年一遇暴雨,利用Geo-studio软件中的Slope/W模块对滑坡进行数值模拟,判断滑坡稳定性状态。结果表明,晒网坝滑坡处于不稳定状态。This paper,taking Shaiwang dam landslide of Three Gorges Reservoir as the research object,according to the geological conditions and characteristics of landslides,slope stability factors combine to select three conditions：①condition one：the natural state（weight）＋status level（135m）;②twoconditions：natural state of＋175 m reservoir water level;③three conditions：natural state of the reservoir water level＋175m＋a rainstorm of 10 year period,the numerical simulation of landslide with Geo-studiosoftware Slope/W module was carried on to determine landslide stability condition.The results showed that Shaiwang Dam landslide is in an unstable state.
