摘要
岩溶地区含水构造不均匀性强，规律性弱，找水工作一直是困扰地质工作者的一个难题。采用大地电磁法和瞬变电磁法在湘南岩溶发育地区开展物探找水工作，并综合对比两者的结果划定了3个主要含水异常区。为了验证其勘探效果的有效性，在异常区施工了一个水文孔SK3孔，钻孔结果显示异常区58．0-58．7m深度含水丰富，表明利用大地电磁法（MT）和瞬变电磁法（TEM）在岩溶区进行地下水勘查有较好的效果，为今后在岩溶地区物探找水提供了实践依据。
Underground water exploration is difficult in karst area, due to heterogeneity and poor uniformity of the water-bearing structures. MT and TEN are used to explore water in the karst area of South Hunan and three water zones are identified. The borehole SK3 to testify the effects shows that there is abundance of water at the depth of 58.0 - 58.7 m, indicating the effectiveness of these two prospecting methods and offering references for water exploration in karst areas in the future.
