三峡工程库区正常蓄水后，库水位在145～175 m间周期性波动，位于库区长江两岸的滑坡体的地下水渗透情况发生了很大的变化，滑坡可能受此影响失稳。以重庆市万州区三舟溪滑坡为例，建立地质模型，采用geo-studio软件模拟了在多种库水位工况和降雨情况下滑坡体稳定性状态，分析滑坡体的稳定性状态变化规律。结果表明，采用支持向量机理论进行滑坡稳定性预测比回归预测具有更好的预测精度。

Since the beginning of testing operation of the Three Gorges Project,after normal water storage of the reservoir area,the reservoir water level is periodically fluctuating between 145 m and 175 m through water level regulation. The great changes have taken place in groundwater perme-ability situation of most of the landslides located on the two sides of the reservoir area of the Yangtze River and because of this the landslides will be unstable possibly in this period. A geological model was built by taking Sanzhouxi landslide located in Wanzhou District of Chongqing as an exam-ple. It simulated the stability situation of the landslide under the various conditions of reservoir water level and rainfall by using Geo-Studio software and analyzed the variation law of stability of the landslide. The outcomes show that the prediction accuracy of landslide stability by using support vector machines theory is much better than that of the regression analysis.
