抽水试验在长沙某地铁车站勘察中的应用

On application of pumping tests in observation of some subway station of Changsha

通过介绍抽水试验基本原理,结合长沙轨道交通1号线某车站施工实例,对地铁影响深度范围内的含水层进行了抽水试验,确定了含水层的水文地质参数,为车站设计的降水工程提供设计依据与研究基础。

According to the introduction of the basic principle of tile pumping tests, the paper combining with some station of No. 1 line track traffic of Changsha, undertakes the pumping tests on the aquifer within the scope of influencing the depth of the subway, and identifies the hydro- logic parameter of the aquifer, so as to provide the design reference and research foundation for the rainfall projects for the station design.
