摘要
为降低深基坑工程设计与施工风险,对东门口站现场实际水文地质情况进行不同工况的抽水试验,取得场地准确水文地质参数(承压含水层)。该抽水试验指导进行基坑突涌性评价和实际工况运行控制情况,为降水运行提供依据对类似工程的设计、施工及风险控制具有借鉴意义。
To reduce the risks of deep foundation design and construction, pumping test has been done on different project conditions for the actual hydrogeology in East Entrance Station on site and the accurate hydro geological parameters (confined aquifer) on site has been obtained. The pumping test has instructed the evaluation of abrupt gush problem in building foundation pit and controlling condition of the actual working situation to provide the basis for water lowering and reference to design, construction and risk control of the similar projects.
