为研究库水位升降对涉水边坡稳定性的影响，选取距三峡大坝坝址56 km 处的谭家河滑坡作为研究对象，探讨了不同库水位升降速率对于滑坡渗流场和稳定性的影响。通过分析 GPS 监测结果，判定谭家河滑坡为典型浮托减重型滑坡。采用 Geostudio2007有限元分析软件，利用 seep / w 模块模拟库水位在145~175 m 之间波动的瞬态渗流场，将渗流场结果应用于 slope / w 模块对滑坡进行稳定性分析。通过数值计算，得到了不同库水位升降速率与边坡地下水位线和稳定性之间的规律，对研究浮托减重型滑坡有一定的参考价值。

To study the influence of reservoir water level fluctuation on stability of the fording landslide,Tanjiahe landslide,about 56 km from Three Gorges Project Dam is selected as a research object. The influence of different water level fluctuation rate on the seepage field and stability is discussed. By analyzing GPS data,it is determined that Tanjiahe landslide is a typical buoyancy weight - loss landslide. The Geostudio2007 software is adopted,and the transient seepage under the water level fluctuation between 145m to 175m is simulated by seep /w module,and the flow field results are used for stability analysis by slope / w module. Through numerical calculation,the relationship of wa-ter level fluctuation rate,the groundwater contour and the landslide stability are obtained.
