在地震波作用下地下连续墙的动力响应

The dynamic responses of the slurry wall subjected to earthquake waves

采用有限元—无限元耦合法分析在地震波作用下地下连续墙与场地土相互作用的动力响应。子结构法的应用有效地解决了有限元—无限元的耦合问题。通过实例分析了El Centro波作用下地下连续墙在场地土中的动力响应,讨论了场地土层性质、厚度以及夹层属性对连续墙动力响应的影响,对地下连续墙的抗震设计具有参考价值。

This paper analyses the dynamic responses of the interaction of the slurry wall and the soil, which are subjected to the earthquake waves, by using the method of finite element and infinite element. The application of the substructure method efficiently solves the combination of finite element and infinite element. The paper discusses the effects on the responses, caused by the feature and thickness of inclusion soil layer. The conclusion can provide the theoretical basis for the design of slurry wall for the earthquake resistance.
