%X 应用ABAQUS 有限元软件, 采用三维有限单元法模拟某基坑开挖过程, 重点分析了格形地下连续墙的水平 位移与应力分布。研究发现, 格形地连墙与一般地连墙的位移分布特征不同, 墙顶位移较小, 墙底位移最大; 内外纵 墙通过隔墙相连增强了整体的稳定性, 隔墙因此处于受拉状态。研究结果可为工程方案设、基坑工程的安全与稳定 性的论证提供依据  Three2dimensional finite element method w as used t o simulate the ex cavation pro cess o f a foundatio n pit and to analyze the ho rizo ntal displacement and stress distributio n of the cellular diaphr agm wa ll.
