Abstract: A 3D nonlinear FEM is used to simulate the strain and stress of Niuniu concrete faced rockfill dam during construction and impounding time; and unified the index curve which academician Shen Zhujiang proposed to analyze the rheology of dam based on the FEM program written by our group. So in each time the stress and strain of dam body can be obtained and the influence of rheology on dam stress and strain. while calculate the displacement of faceplate slot and peripheral slot, 3D Submodel method is used. Base on actual construction and impounding process, amend the displacement of dam upriver surface before each stage faceplate being built. face-to-face fiction contact element between concrete face and dam body to simulate the strain and stress of the faceplate. So some helpful suggestion can be provided for the further optimizing design of the dam.

Key words: concrete faced rockfill dam, Duncan-Chang model, rheology, FEM, 3D submodel
