摘要
将有限元方法应用于黄土地基的震陷量预测 ,定量地研究了黄土地基地震沉陷特性与场地条件、基础形式、土动力特性等因素的相关关系 ,为黄土地基基础的抗震增稳设计与处理提供了科学依据 .
In the study, the FEM(Finite Element Method) are used to predict the seismic subsidence, and the relations, among the subsidence characteristic of loess ground and the site, the foundations, the soil dynamic property, can be studied quantitatively. As a method, it can provide the theoretical laws for seismic design and seismic resistance. At the same time, loess dynamics used in earthquake engineering is developed greatly.
