Abstract: Taking a reservoir bank slope as example,based on the geological environment study data, using SEEP / W module of GEO-SLOPE software,the seepage field of the reservoir slope under reservoir water level fluctuation is simulated comprehensively. The seepage characteristics and variation,water-rock interaction under water level changes of highly weathered argillaceous sandstones and marl rock formed slopes which are widely distributed around reservoir bank are analyzed from three stages of reservoir water level fluctuation,rising,steady,and dropping; pore water pressure and seepage flow velocity of the slope around reservoir bank are analyzed. The computational results provide a basis for further study of interaction between seepage and the deformation of reservoir bank slope.
