地铁车站暗挖施工PBA中地下水处理措施研究

Research on Groundwater Treatment Measures in Tunneling PBA Construction of Subway Station

为保证地铁工程施工顺利进行,需要对工程范围内的地下水采取合理有效的防治措施。论文分析暗挖工程地下水处理的重要性,结合北京某地铁站施工案例,详细阐述地铁车站暗挖PBA施工中的地下水处理措施,包括止水施工方法、确定试验段、分区钻孔和注浆布置、深孔注浆。

In order to ensure the smooth construction of subway project, reasonable and effective prevention and control measures should be taken for groundwater involved in the project. This paper analyzes the importance of groundwater treatment in underground excavation project, and elaborates the groundwater treatment measures in tunneling PBA construction of subway station based on the construction case of a subway station in Beijing, including sealing construction method, determination of test section, partition drilling and grouting layout,deep hole grouting.
