地铁车站深基坑降水方案设计

Dewatering Design for Deep Foundation Pit of Metro Station

根据深基坑降水方案设计的基本原则以及工程地质、水文地质条件,介绍了合理的现场抽水试验及水文地质参数的计算方法,在此基础上分析了天津地铁沙柳路车站深基坑开挖所采用的管井井点降水方案的设计情况。按该方案顺利地完成了基坑的施工。

In this paper, based on the basic principle of ground-water lowering schematic design foundation pit and the condition of engineering geology and hydrogeology, a reasonable field pumping calculating method are introduced and a design of dewatering and for deep test and drainage by pipe well point method for deep foundation pit excavation of a metro station in Tianjin city is presented, based on which the construction of foundation pit was successfully completed.
