摘要
本文以山东省东阿县下马头水源地为实例,探讨了大型抽水试验的主要水文地质意义,包括:确定地下水的主要补给来源及方向,抽水影响范围及程度,水源地岩溶含水层的富水性及供水保证能力,水源地附近地下水与地表水之间的水力联系,水源地附近主要断裂构造的水力性质,水源地抽水对下游水源地的影响以及水文地质参数与水源地地下水允许开采量计算。
Exemplified by the Xiamatou groundwater wellfield in Dong＇ e County, Shandong, the hydrogeological functions of a large pumping test is discussed in this paper. Based on data of a large pumping test, the followings can be determined： the recharge sources and their directions, influence scope and extent of the pumping test, aquifer productivity and guarantee capacity of water supply, hydrologic relationships among the karst water, porous water and Yellow River, hydrologic characteristics of the main faults around the wellfield, influence of the test on the neighboring wellfields, as well as hydrogeologic parameters and available well yielding.
