摘　　要：结合上海市区具体工程的施工控制情况,通过增加、降低地下连续墙刚度和内支撑刚度的大小,采用两维施工模拟有限元技术,详细探讨了上述刚度变化对围护结构的变形和内力的影响,并比较两者的影响程度。Combined with the construction control of a certain project in Shanghai,the paper studies in detail the effect of the diaphragm wall and brace stiffness on the deformation and internal force of the retaining structure,through increasing or reducing the stiffnesses.The two dimensional FE technique to simulate the staged construction of deep excavation is used.The good results can guide the project construction.

关 键 词：地下连续墙 刚度 围护结构 变形 内力
