| 摘 要： | 本文用“工程近似”方法研究了饱和砂土对地震的动力响应。根据饱和砂土对循环荷载动态响应的机理建立了简化模型，给出了描述动态响应的动力方程和描述孔压产生与消散的扩散方程。用Ｎｅｗｍａｒｋ方法与有限差分数值求解这些方程。求得了饱和砂土层对地震的动力响应，包括孔压、剪应力与表面加速度的变化，并对数值结果进行了分析、讨论。

| Abstract: | The dynamic response of sat urated sand deposits to earthquake loading isinvestigated through an“Engi neering Approach”.Considering the mechanism of dynamicresp onse of s at urated sands to cyclic loading,a simplified model is constructed,and theequation for describing the response and the diffusinn equatfon for describing generationand dissipation of porewater pressure are given.These equations are solived numerically by the Newmark’s method and finit edifferences method,The dynamic response of a satnrat... |
