傍河型地下水源地的数值模拟——以河南三门峡市辛店水源地为例

Numerical simulation of goundwater resource areas along river-taking Xindian groundwater resource areas in Sanmenxia as the example

本文通过对三门峡辛店水源地地质、水文、气象条件的正确分析和对水文地质概念模型的正确认识及边界条件的合理概化,建立地下水流二维非稳定流数学模型进行数值计算,对开采性抽水试验地下水位变化进行模拟。结果表明,该模型适用于刻画傍河型水源地地下水流场的变化,用来对水源地开采动态进行预测也取得了良好的效果。对同类地下水源地的数值模拟具有一定借鉴意义。

Through analyzing and researching on the data of the geology, hydrology and climatic phenomenon for Xindian groundwater resource areas in Sanmenxia, the mathematics model of 2-D transient seepage is established and used to estimate the change of groundwater under the condition of the exploitation pump tests. The results show that the evaluation model is fit for depicting the changes on the transient seepage of groundwater resource areas along river. The model is used for the prediction of the exploited trends of groundwater resource areas and the practical results are obtained, which provides the valuable experience for the evaluation of the same type groundwater resource areas.
