| 摘 要： | 双排格形地下连续墙作为基坑工程的一种新型自立式支护结构,不仅可以发挥地连墙的作用,还有着墙体刚度大、抗渗性好、无需安装内支撑的优点。本文以某深基坑工程为例,采用有限单元法模拟基坑开挖与降水,重点分析双排格形地下连续墙的空间变形特性。

| Abstract: | The double-row cellular continuous diaphragm wall is a new type of self-supporting enclosure structure for construction of foundation pit. It cannot only play the role of the continuous diaphragm wall， but also has the merits of high stiffness of wall， better impermeability and without inner support. By taking the construction project of a deep foundation pit as the study case， the characteristics of the spatial deformation of the double-row cellular continuous diaphragm wall is emphatically analyzed herein by the simulation made on the excavation and dewatering of the foundation pit with the finite element method concerned. |
