Abstract: Numerous wading landslides formed in Three Gorges Reservoir.Water level cyclical fluctuations causes the changes of properties of the rock-soil bank landslides,also make the changes of seepage field and the stability of the landslides.This paper studies the response of the wading landslide’s stability induced by water level fluctuation.It analyses the hydrodynamic pressure landslide using the classification of significant wading landslide in Three Gorges Reservoir.It takes the Zigui Shuping Landslide as a case study.The SEEP and SLOPE modules Geo-studio software are used to model the process of seepage field and calculate the stability,analyzes the law of effect hydrodynamic pressure landslide under different permeability coefficients of the landslide and the water level rate.The results show that the groundwater level has a concave phenomenon and the stability coefficient increases whenthe reservoir water level rises.The groundwater level has a convex phenomenon and the stability coefficient obvious decreases when the reservoir water level reduces for hydrodynamic pressure landslide.The reservoir water level fluctuation has the larger rate,and the permeability coefficient is smaller.The reservoir water level fluctuation has more obvious effect on the seepage and stability of the landslide.
