基于透水性地层地铁基坑地下水处理工法研究——以福州地铁建设工程为例

Research on Underground Water Treatment Method of Subway Foundation Pit Based on Permeable Stratum——Take Fuzhou Metro Construction Project as an Example

地铁车站基坑开挖过程中,经常出现突涌、地下水无法抽干的情况,严重威胁着基坑自身及周边环境的安全。基此,分析了透水性地层的地铁基坑开挖过程遇到的抗突涌稳定、地下水无法抽干等问题原因,论证了地下水处理的必要性,并提出了有效解决途径及方法。

During the excavation of the subway station foundation pit,there are often sudden surges and the groundwater cannot be drained,which seriously threatens the safety of the foundation pit and the surrounding environment.Based on this,the reasons for the problems of anti-surge stability and groundwater cannot be drained during the excavation of foundation pits in permeable stratum are analyzed,the necessity of groundwater treatment is demonstrated,and effective solutions are proposed.
