abstract="This paper carries out the 3-D nonlinear numerical simulation of the dam body and base with the finite difference method in the consideration of the real condition of the concrete gravity dam of a hydroelectric station in Yunnan province. First of all, an integrated three-dimensional calculus model is set up, and the geological structure system is simulated. And then, the strain-stress relationship of the bedrock is simulated by the elastic-plastic constructive model and Mohr-Coulomb yield criterion. At last, the strain-stress distribution and the development law of plastic zone are analyzed under normal impounded level as well as overload level, and the weak point of the bedrock was thus exposed.<p />",
