Abstract：Based on the collected creep deformation data of CFRD built on riverbed alluvium,the back analysis for calculation parameters and creep deformation parameters of dam materials was performed.According to the results calculated by the back analysis,the distribution of stress and strain in the dam body,foundation,concrete face slabs,concrete diaphragms wall and toe slabs was studied by the double yield surface elasto-plastic model and three-dimensional FEM.Some valuable results were obtained.It was shown that the creep deformation of the dam body and foundation was on a small level and tended to be stable.
