Abstract	The variations of water level in reservoir have significant to the stability of the reservoir slope. Analyzing the influence factors which fluctuation of water table for slope by the Finite Element Method and Limit Equilibrium Method. Analyzing the stress field, strain field and stability for Jiu-zi collapse deposit in different reservoir water level, and getting the results that the distribution characteristics stress and strain in different water level. Using FEM based on shear strength reduction methods and Limit Equilibrium Method, results show: (1) The numerical value of horizontal displacement and shear stress is the largest in the low water level, as the water level rises, the value become decrease. (2) As the water level rises, stability coefficient increases, therefore, it is less likely to cause deep slip. (3) The former have a larger numerical value than the latter with the FEM based on shear strength reduction methods and Limit Equilibrium Method.
