| Abstract: | A three|dimensional nonlinear analysis method of static stresses and deformations and seismic dynamic response is developed and the computer program is worked out for earth or rockfill dams and subsoil foundations. The static analysis is based on the Duncan|Chang hyperbolic stress|strain model and incrementally|iterative nonlinear numerical algorithm. And nonlinear behavior of soil materials in the dynamic analysis is taken into consideration by using the time|domain equivalent linearalized procedure. Numerical computations for Pubugou cored rockfill dam with the height of 188 m are performed considering its actual canyon shape and local topographical condition. The computation results can offer the helpful basis for the engineering design of this dam. |
