摘要
以上海董家渡金融城工程超大深基坑为例,通过开展专项水文地质试验,分析了基坑所面临的承压水综合治理风险,进而提出在群坑耦合基础上的降水设计思路。通过现场承压水试抽水试验,提出了合理的降水运行方案,制订了相应的配套措施并实施,达到了预期的地下水控制目标。
Taking the ultra-deep foundation pit of Shanghai Dongjiadu financial city project as an example,and through carrying out specific hydrogeological tests,a comprehensive risk treatment of confined water in the foundation pit is analyzed and then a design idea of water-lowering on the basis of group pits coupling is proposed. Through the trial pumping test of on-site confined water,a rational water-lowering operation scheme is put forward, the corresponding supporting measures are set out and implemented and the expected groundwater control objectives are achieved accordingly.
