Slope of reservoir is a kind of important project geological problem and reservoir water level change is a crucial factor to affect slope distortion and distortion. Doing ration research of slope stability with reservoir water level change has basilica instruction meaning for treatment and forecasting of landslide.Zhaigoucun landslide which locate at middle-upside of Three Gorges Reservoir in Chongqing is 87 km away from Chongqing and is 525-545km away from Three Gorges Reservoir. At present the suiface of Zhaigoucun landslide and some house on zhe landslide show rip and sink distortion, which will ceaseless develop in future. The slope will occur slide because of movement of reservoir’s water line. This may be excitating and prick up distortion of the slope, which will endanger engineering and resident’s safety of lives and property.The text take the case of Zhaigoucun landslide to research slope of reservoir. In the first place, the geological conditions and influence of Zhaigoucun landslide are analysed. In addition use water level change as a research object. In the second place, analyse the influencing factors of slope when water level change, apply seepage theory to seepage analyses of water level change and use limiting balance method analyse stability of slope. In the end, calculating seepage field and coefficient of safety about several conditions provide reliable evidence for for treatment and forecasting of landslide.Based on a practical example of Zhaigoucun landslide, the method of analyzing stability of slope for movement of reservoir’s water line is formed. The results of this research has reference value to forecast and criticize stability snalysis of slope due to reservoir water level change.
