摘要: 徐州某地铁车站为地下两层岛式站,车站下伏基岩倾角较大,岩性分布呈条带状,构成相对独立的含-隔水条带,为急倾斜非均质含水层,现有解析法难以充分反映其水力响应特征;运用Visual Modflow软件,构建急倾斜非均质含水层数值模型,反演拟合确定了能充分反映其特性的水文地质参数,为降水设计施工提供了准确参数。

Abstract: The bedrock underlying a subway station is steeply inclined and can be considered as an independent aquitard. The soil above the bedrock is a heterogeneous steeply inclined aquifer. The current analytical solution methods could not be readily applied. The Visual Modflow was used to establish the seepage model in this nonuniform aquifer. The seepage parameters can be obtained from the back analysis results.
