摘要

根据地质及结构特点，建立了能反映框格式地下连续墙力学特性的典型子模型，即槽段有限元模型。基于ABAQUS有限元软件，采用经典的摩尔-库仑（Mohr-Coulomb）屈服准则、非关联流动法则，对框格式混凝土地连墙槽段进行了施工全过程模拟，详细分析了结构在最不利工况下混凝土连续墙的应力与变形，还用强度折减有限元方法分析了该最不利工况下结构的整体稳定性，论证了框格式连续墙这种地基处理方式的合理性与可行性，地下连续墙在应力变形及稳定方面能满足工程需要。

Abstract

According to the characteristics of the geology and structure

a sub-model which contains the mechanical characters of the underground continuous wall is built. Based on ABAQUS software

Mohr-Coulomb failure criterion and non-associated flow rule are used to simulate the course of construction. The stresses and displacements of the structure are analyzed amply. Meanwhile

based on the strength reduction method

the stability of the structure is studied. The results show that the constructing method of the groundsill using underground continuous wall is reasonable and feasible. So

the underground continuous wall can satisfy the requirement of engineering.
