摘　　要：文章通过使用Midas/GTS有限元软件对某锚碇圆形地下连续墙基础在不同开挖方式下的应力、应变及地下连续墙应力、应变对结构几何尺寸的敏感性进行数值模拟,分析地下连续墙桥梁工程施工阶段的特点。结果表明,采用平挖方案和不对称开挖方案时,地下连续墙的变形及应力均能满足施工监测预警值要求,不会使得支护结构产生较大变形。By using Midas / GTS finite element software,this article conducted the numerical simulation for the stress,strain and diaphragm wall stress,and the sensitivity of strain to structure geometry of circular diaphragm wall foundation of an anchorage under different excavation methods,and analyzed the fea-tures of diaphragm wall bridge construction phase. The results showed that,when using the flat excava-tion program and asymmetrical excavation program,both deformation and stress of diaphragm wall can meet the requirements of construction monitoring and warning value,and the supporting structure has no greater deformation.
