Abstract A large deformation rock mass with a volume of 1 000 m3 is in the right bank of Longkaikou hydropower station，whether it is stable or not can directly affect the construction of the project and its permanent safe operation，so the stability and deformation of the plasmodium needs to be analyzed and studied completely. Using the strength reduction method based on FLAC finite difference，in this paper，the stress-strain relation of the plasmodiums typical section plane III–III is respectively analyzed under the primitive condition and the earthquake circumstance. Studies show that，comparing with the traditional grid limit equilibrium method，this paper can define the distortion pattern of land-side，the plastic yielding area. The study result is of great significance to the stability and the safe operation of Longkaikou Hydropower Hinge.

Key words： rock mechanics plastic yielding strength reduction method stability parameter
