Abstract Coupling analysis of the seepage field-stress field is a hot and difficult problem in the study of stability for deformable body under water level change in reservoir area. The discontinuum-based discrete element method is a fully fluid-solid coupling analysis method，which can simulate the fluid flow between fractures of the impervious rock mass. Taking the Baishadiao deformable body at right bank of the Xiluodu hydropower station in Jinshajiang river as a case study，the mechanical properties of rock slope parameters are obtained with various tests；according to the reservoir operation curve of the Xiluodu hydropower station，based on full consideration of the regional geological condition of the bank slope，stability analyzing of the deformable body under reservoir water level change has been carried out with the discrete element method；the limit equilibrium analysis based on the calculation of seepage field is also carried out for a comparative analysis. The simulation result shows that with increase of the reservoir water level，the pore water pressure increases，and stability gradually decreases；at a water level of 600 m，instability failure of the deformable body is observed；compared with the limit equilibrium analysis，the discrete element method considers the dynamic flow of the water in the cracks and can reflect the actual situation.

Key words： rock mechanics Xiluodu reservoir area deformable body water level change discrete element method(DEM) mechanics-fluid coupling
