| 摘 要： | 作为"两墙合一"的地下连续墙插入含水层中深度的变化对基坑降水效果改变十分明显。本文结合武汉地铁2号线范湖车站深基坑工程实例,通过三维数值模拟,详细对比了不同深度的地下连续墙内基坑降水场地地下水渗流场的变化。在此基础上,分析总结出了地下连续墙埋置深度对基坑降水的影响规律。

| Abstract: | The dewatering effect in the foundation pits varies greatly with the embedded in aquifer of the dual-purpose diaphragm walls. In this paper, taking the Fanhu station in Wuhan Metro Line No. 2 as an example, using 3D numerical simulation, the change of the groundwater seepage field in foundation pit is compared with different diaphragm wall,s embedded depth. On this basis, the influence rule of diaphragm wall＇s embedded depth on foundation pit dewatering is analyzed and summarized. |
