深基坑降水试验分析

Analysis of Deep Foundation Pit Dewatering Test

某深基坑降水工程地处南京河西地区且临近地铁,为确保基坑安全,在土方开挖降水前进行了基坑降水试验,以指导后期开挖过程中的降水方案。通过对试验方案及试验结果的分析,基坑内降水对坑外水位影响较小,表明基坑止水帷幕质量较好,获取的降水参数和试验数据可以指导后期土方开挖过程中降水,并提出合理化建议。

Dewatering of a deep foundation pit in Nanjing Hexi area and near the subway, in order to ensure the safety of foundation pit, the pit pumping test was conducted in the excavation before precipitation, the precipitation scheme to guide the later in the process of excavation. In this paper, through the analysis of the test plan and test results, some suggestions on the process of precipitation later excavation are proposed.
