组合型水泥土挡墙的弹塑性有限元分析

Elastic-plastic FEM Analysis on the Composite Support Structure of Cement-soil Gravity Retaining Wall

对常见组合型水泥土挡墙围护结构作了简单介绍,并结合实际工程,采用H-S模型对含组合型水泥土挡墙围护结构的基坑工程整个施工过程中围护结构的变形、和施工造成的相邻道路的位移、沉降进行弹塑性有限元分析;同时,将计算结果与工程中得到的监测数据进行对比、分析,得出了有益的结论并指出存在的问题。

This paper introduces some familiar types of the composite support structure--cement-soil gravity retaining wail is introduced. An elastic-plastic analysis is mainly carried out by FEM on the internal force and deformation of retaining wall as well as the displacement and settlement of surrounding roads during the whole excavation process. At last, we got some useful conclusions and pointed out existing issues in the deep pit design from comparing the result of FEM analysis with the data from field measurement
