摘要
查明太行山缺水地区变质岩裂隙水水文地质特征与其电性特征之间的关系,有助于分析该地区基岩裂隙水的赋存规律。阜平县是典型的太行山变质岩缺水地区,根据区域地质资料,采用音频大地电场法、放射性法、音频大地电磁法和激电法对比研究了变质岩裂隙水的电性特征,形成了一套高效合理的寻找地下水富水部位的技术方法组合。结果表明,阜平县变质岩裂隙水地区水文地质特征与其电性特征之间具有明显的一致性。阜平县变质岩基岩裂隙水地区的地下水勘查具有很强的实践意义,为此类变质岩分布区地下水的找寻起到了示范作用。
The relationship between the hydrogeological properties and electrical responses of metamorphic rock fissure water in water-shortage areas of Taihang Mountains has perplexed geologists for a long time. The metamorphic rock area in Fuping County is a typical water-shortage area. Based on the regional geological data, we studied the hydrogeological properties of the metamorphic rock area in Fuping County. We found out the occurrence patterns of the strata, geological structure, and metamorphic rock fissure water. On this basis, we studied the electrical responses to the hydrogeological properties of metamorphic rock fissure water using audio frequency telluric electricity field method, radioactivity exploration, audio frequency magnetotelluric method, and induced polarization method. Geological drills were arranged to test and verify the degree of correspondence between the hydrogeological properties and electrical responses. The results showed that there is evident one-to-one correspondence between the hydrogeological properties and electrical responses of the metamorphic rock fissure water in Fuping County. The groundwater exploration in the metamorphic rock fissure water area in Fuping County has huge practical significance, and it will serve as an example for finding groundwater in other metamorphic rock areas of this type.
