| Abstract: | 3D elastoplastic finite element method is applied to analyse Jinzhong concrete-faced rockfill dam.The material zoning,the construction and storage processes,and the joint of face slab in three directions are simulated.A kind of elastoplastic model with double yield surfaces is used to simulate the characteristic of the rockfill's deformation.According to the result of numerical analysis,the distribution of stress and deformation of the dam in completion and storage stage are discussed. |

| Keywords: | concrete-faced rockfill dam stress deformation double yield surface model 3D-FEM Jinzhong |
