摘要
Abstract
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.关键词
