综合物探方法在湘中贫水山区找水中的应用

湖南省隆回县荆枝村为典型贫水山区,其中龙潭组砂页岩大面积出露于村落四周,灰岩分布面积十分有限.为解决该地区饮水困难问题,在综合研究该区地形地貌特征和地质情况的基础上,投入高密度电阻率法、激电测深和音频大地电磁测深进行地下水资源勘查.通过靶区刷选,在典型异常处布设了3个钻孔,出水量分别为32 m3/d、347 m3/d和256 m3/d,有效解决了当地饮水问题,证明了综合物探方法在该地区地下水资源勘查中的重要性.

The application of multiple geophysical methods to water exploration in the arid areas of central Hunan Province

Longhui County in Hunan Province is a national poverty area.Jingzhi Village in this county has an arid area.Sandstone and shale of Longtan Formation are exposed extensively in the village,and the distribution of limestone is very limited in the northwest and the south.In addition,the relatively high ground level leads to surface water scarcity,which seriously affects the normal life of local villagers.To solve the problem of drinking water in this area,the authors carried out a comprehensive study of the topography and geological features of the area and,on such a basis,employed the high-density electrical method,AMT sounding and IP sounding methods and arranged drill holes ZK01,ZK02 and ZK03 These three holes all meet water,with the outburst water quantity being respectively 32 m3/d,347 m3/d and 256 m3/d,thus solving the problem of drinking water.It is proved that the comprehensive geophysical method is effective in the exploration of groundwater resources in this area.
