The safety is first-class important event of the dam. The crash for the gravity dam usually causes due to slid, the slippery stable is a key problem of big dam. This paper checks the stability of one dam by rigid body limit equilibrium method and finite element technique. Rigid body limit equilibrium method is a kind of traditional stable analytical method, which is confirmed by factual engineering, the safe coefficient is always used to judge the big dam safety degree. 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 paper compares the two methods and makes sure the fact that the finite element is more reasonable than rigid body limit equilibrium method for analyzing the stability of gravity dam.
