Abstract:: By the rock mass combination,bedding slope characteristic and rock mass features of a hydropower plant right bank slope,based on analyzing the deformation indication and the rock mass structure survey,then geological model was established.The deformation failure mechanism was discussed thoroughly by the FLAC3D numerical simulation.The results indicated that the slope deformation mainly is characterized as creeping-ripping along the bedding surface,the deformation body boundary is controlled by soft rock strata and rock mass structure,middle and upper part of slope slide along weak intercalated layer,the locked section appear local bending and deformation because lower rock mass is restricted,at the same time,upper rock mass appear fracture deformation and based on the process form progressive destruction;By the upper rock mass thrust,in fragmentation rock mass form shear sliding surface gradually and run-through with the slip-cut face of bending parts,and then may form the final destruction.Based on the failure model,the stability of deformation body was analyzed,and then the measures that adopt to anchor to reinforce the locking segment was proposed
