The finite element technique is a method which is quickly developed in the calculator science and the basic theories of the rock soil mechanics.
The base parameter of material as follows: concrete density γc=2400Kg/m3,water density γ0=1000kg/m3, sediment buoyant density γc=900Kg/m3.
Conclusions From above calculating result about anti-sliding stability safety factor of the gravidity dam by rigid body limit equilibrium method and FEM, we can get conclusions as follows: the safety factor from rigid body limit equilibrium method is bigger than that from FEM, it signals that rigid body limit equilibrium method is more safe and conservative than FEM. the result from FEM is closer to the gravity dam because it accord with the project fact by considering uneven material.

The rigid visco-plastic FEM is the main numerical simulation method in the metal bulk forming and its basic equation is based on the Euler coordinate system.The basic assumption of the rigid visco-plastic flow theory is[4,5]: ignoring the elastic deformation of the material and the quality stress and the inertia force; the materials in even quality and having the same character of their directions; the volume of the material not changing; the materials abiding by the Mises yield criterion and strengthening at the same direction; the rigid-plastic material changing only on strain hardening while the rigid visco-plastic changing on both the strain hardening and strain-rate hardening simultaneously.
