Abstract：This study focuses on the slope deformation characteristics and mechanism in the left bank of Baihetan hydropower station on the Jinsha River. As the unloading deformation develops with the erosion of the river in geological history，the rock mass on the slope at different elevations and localities has various deformation features. It is very important to study these features. Based on the investigation data，the deformation controlled by the slightly-inclined angle dislocation interfaces as well as the NW fault zone mainly was simulated by the distinct element numerical analysis code UDEC and 3DEC after the development mode of unloading deformation was summarized，The controlling effect of key structureal plane was illustrated during the erosion of the river，proving the geological analyses further. The slope deformation mechanism was analyzed in combination with the geological investigation and numerical calculation results。
