摘要：
In order to study the influence of water level fluctuation on the stability of landslide in the Three Gorges Reservoir (TGR), Xigouwan landslide was selected to be a research object to analyze its deformation mechanism as the fluctuation of the reservoir water level. Based on the long-term field monitoring of landslide, the evolution law of the surface has been studied. Based on the numerical simulation used by FLAC(3D), five different water levels of TGR operating conditions are set, and the plastic zone, the factor of safety, change of displacement, and the seepage characteristics of the landslide were obtained to analyze the influence of water level fluctuation on the stability of landslide.
