| Abstract: | Based on the representative soil layer distribution in Shanghai and its mechanical parameters, the authors select and build a few computation profiles. The effects of ground water table, silty sand thickness and its depth on the ground peak acceleration and displacement are calculated by means of drained effective stress analysis method incorporating Biot dynamic consolidation equations and a bounding surface hypoplasticity model. Some results are useful. |
