摘　　要：水文地质参数是富水区域地下结构设计不可缺少的重要指标。临江地层复杂,计算确定透水层水文地质参数存在一定的难度。以南京越江隧道工程深达44.45m的超深基坑为例进行抽水试验,利用所观测数据采用传统的解析法公式和数值法进行参数反演分析,对目的含水层进行水文地质参数求取,并通过观测水位数据对所求参数进行修正,取得了比较符合实际的水文地质参数。本试验为基坑开挖提供了所需的水文资料,取得了良好效果。Hydrogeological parameter is an important index of underground structure design in water - rich stra- ta. It is difficult to determine hydrogeological parameters in complex strata. This article takes the pumping test of the deep excavation with 44. 45 m in Nanjing tunnel engineering for example. The traditional analytical method and nu- merical method are used to back analyze the parameter , and the hydrogeological parameters of aquifer are obtained. The actual hydrogeological parameters are obtained, and the necessary hydrological data is provided for excavation of foundation pit.
