基于Geo-studio的晒网坝滑坡稳定性分析

摘要

This paper,taking Shaiwang dam landslide of Three Gorges Reservoir as the research object,accord-ing 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.%　　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。
