The slope which is composed of deep accumulation body is widely distributing in southwest of China.The stability calculation of the accumulation body is mainly influenced by the deformation and failure mode and the mechanical parameters.A accumulation body on the left of a hydropower station which is located in YaLong river was used as an example.The boundary conditions and the deformation and failure mode of the accumulation body was analyed, and the strength parameter of the accumulation body was analysed by engineering analogy method、laboratory test method and inverse analysis method. Comprehensive determination of the strength parameter of the accumulation body consideration to the difference and the Limitation between these methods.
