英文摘要	The impoundment and running of Three Gorges Reservoir makes the water level fluctuate between 175m and 145m, and the water level fluctuation has been leading to the seepage field variation of bank slopes, which will bring out the stability change of bank slopes. In order to obtain the relationship between the angles of dip and factors of safety of bedding rock slopes which are generalized slope models from some bedding rock slopes failure in some reservoirs, the finite element method based on Darcy seepage theory was taken to simulate the seepage field variation of this type of bedding rock slopes when exposed to water level fluctuation, then the underground water tables of the bedding rock slopes with different angles of dip were obtained, finally the factors of safety of bedding rock slopes when water level rose and fell at speed of 0.2m/d were calculated by limit equilibrium method. Through the regulation analysis of factors of safety with the increase of angles of dip of bedding rock slopes when exposed to reservoir water level fluctuation, the relationship between factors of safety and angles of dip of bedding rock slopes was obtained.
