开采性抽水试验在平凉太统山岩溶水水源地勘查中的应用

Application on the Exploited-pumping Test in the Investigation of Karst Water Source Place in Pingliang Taitong Mountain Area

平凉太统山岩溶水地处两大构造带的复合部位,地质作用强烈,构造发育,水文地质条件复杂,资源评价难度很大,运用开采性抽水试验就成为最有效的地下水资源评价方法之一。该法用于平凉太统山岩溶水水源地的勘查,不但能确定可靠的地下水允许开采量,而且可为岩溶水水文地质特征的进一步认识提供重要依据。

<Abstrcat> The Karst water of Pingliang Taitong montain area is located in the compounding place between two large structural units. The geological function is strong and its structure up growth and hydrological condition are complex, so it is difficulty to evaluate the resources. The application of the exploited-pumping test is one of the most effective methods for water resources evaluation. The method is used in the investigation of the karst water source in this area, which not only can determine the reliable exploitable volume of groundwater, but also can provide the important basis to furthermore known hydrogeological characteristics of karst water.
