太行山缺水地区变质岩裂隙水水文地质特征及其电性响应--以阜平县为例

摘要

The relation of metamorphic rock fissure water between hydrogeological properties and their electrical responses perplexed geologists for a long time in water shortage area of Taihang was presented. With regional geo-logic data, hydrogeological properties of metamorphic rock in Fuping County was studied. Characteristics of strata, structures and metamorphic rock fissure water were found out. On this basis, electrical responses to hydrogeological properties of metamorphic rock fissure water were studied by audio frequency telluric electricity field method, radio-activity exploration, audio frequency magnetotelluric method and induced polarization method. Geology drills were distributed to test and verify their degree of equivalence. The results show that there is evident one-to-one match between hydrogeological properties and their electrical responses.%太行山缺水地区变质岩裂隙水水文地质特征与其电性响应之间关系的研究是长期困扰地质学者的一个大难题。根据区域地质资料，进行了阜平县变质岩地区水文地质研究，查明了该地区的地层、地质构造和变质岩裂隙水的赋存规律。在此基础上，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水文地质特征的电性响应；并布置地质钻孔验证了水文地质特征与电性响应之间的对应程度。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响应之间具有明显的一一对应关系。
