| Abstract: | The three-dimensional finite element analysis is adopted to simulate and calculate the stresses and deformations of Shuangjiangkou Core Rockfill Dam with Duncan-Chang EB nonlinear model during its completion and operation periods by incremental loading. Based on three parameter proposal of different strengths, the analysis of sensitivity to parameter is carried out; and the distribution rule of stresses and deformations is given. The results show that the stresses and deformations of dam are allowable; and the design proposal is reasonable. |
