物探技术在湘西南岩溶丘陵区地下水勘查中的应用

Application of Geophysical Exploration Technique in Groundwater Exploration in Southwest of Hunan Karst Hilly Region

摘要:

物探技术被广泛应用于地下水资源勘查工作之中。综合运用高密度联合剖面法，高密度电测深法和微动法进行综合探测，查明湖南省武冈市东北部水浸坪乡打井找水有利靶区，结合水文地质条件确定钻孔位置，并对其进行成井施工验证，钻孔涌水量达323m3/d，效果显著。研究结果表明，科学合理选择地球物理勘探方法组合，可有效提高地下水勘探的效率。

Abstract:

Geophysical prospecting technique has been widely applied to groundwater resources exploration work. By using integrated use of highdensity combined profiling method, high density electric sounding method and micro method，favorable targets for exploring underground water in northeast of Shuijinping town in Wugang city of Hunan province have been found. Combining with hydrogeological conditions, the position of the holes has been determined. As showed by the test of wellforming, the inflow of water can reach 323m3. It is showed that scientific and reasonable choice of geophysical exploration method can effectively improve the efficiency for exploring groundwater.
