摘要
本文根据上海市区的典型地层分布及其力学参数,选取和构造了若干计算剖面,利用Biot动力固结方程和亚塑性边界面模型的排水有效应力动力分析方法,计算了地下水位、粉砂层厚度及其埋深等对地表峰值加速度和位移的影响,得到了一些有意义的结果。
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.
