地铁车站深基坑降水实例分析

伴随着我国基础设施建设的大力发展,深基坑的应用越发广泛,其中基坑降水工程对基坑的稳定起着关键作用。文章以天津地铁某车站为例,针对所处区域地下水分布特点,通过分析、计算确定该车站疏干井布置数量及深度。并经现场抽水试验及实际水位监测验证,基坑内降水效果满足降水设计要求,降水工程对周边环境影响较小。文章研究结果旨在为指导基坑降水工程提供实例参考。

With the vigorous development of our country's infrastructure construction,the application of deep foundation pits has become more and more extensive.Among them,foundation pit dewatering works play a key role in the stability of foundation pits.This paper takes a certain station in Tianjin Metro as an exemplar,according to the distribution characteristics of groundwater in the area,through analysis and calculation,the number and depth of the drainage wells of the station are determined.And verified by field pumping test and actual water level monitoring,the dewatering effect in the foundation pit meets the design requirements,and the dewatering project has little impact on the surrounding environment.The research results of this paper are intended to provide practical reference for guiding foundation pit dewatering engineering.
