摘要
本文以南京地铁十一号线六合区政府站为例,根据分层抽水试验资料,利用稳定流公式法、非稳定流泰斯配线法、直线图解法和水位恢复法计算出潜水及承压含水层的水文地质参数。基于车站场地的地质条件,对以上多种方法的计算结果进行对比分析,从而优选出参数,为车站基坑降水设计提供可靠的依据。
Liuhe District Government Station of Nanjing Metro Line 10 is adopted as an example in the paper.Steady flow formula method,unsteady flow tice wiring method,linear graphic method and water level recovery method are utilized to calculate hydrogeological parameters of phreatic water and confined aquifer according to stratified water pumping test data.The calculation results of the above methods are comparatively analyzed based on the geological conditions of the station site,thereby selecting parameters and providing reliable basis for the design of the foundation pit precipitation of the station.
