摘　　要：本文介绍了高密度电法在莱州市虎头崖镇埠后村地下水勘查中的具体应用。在系统总结区内地质及水文地质条件、地球物理特征基础上,项目组于埠后村周边开展了L1、L2、L3剖面高密度电法测量,结合已知断裂构造的验证约束,圈定了断裂交汇处且受北西向张扭性断裂控制的低阻异常中心为导水储水有利部位,验证了高密度电法在埠后村地下水勘查的有效性。本次工作为相近花岗岩地区寻找富水断裂提供了技术思路;基于已知断裂构造的验证约束,可进一步提升物探解译的准确性和布设孔位的科学性,能有效避免或减少后期钻探人力财力成本的浪费。This paper introduces the application of high-density electrical method in groundwater exploration in Buhou Village,Hutouya Town,Laizhou City.On the basis of systematic summary of geological and hydrogeological conditions and geophysical characteristics in the area,the project team carried out high-density electrical measurements of L1,L2 and L3 profiles around Buhou Village.Considering the constraints of known fault structures,the intersection of faults and the low-resistivity anomaly center controlled by the NW tensional-torsion fault are delineated as the favorable location for water conduction and storage.The validity of high-density electrical method has been verified for groundwater exploration in Buhou Village.This work provides technical route for finding water-rich faults in similar granite areas.The constraints of known fault structures can further improve the accuracy of geophysical interpretation and the scientificity of borehole placement,and reduce the waste of manpower and finance in followup drilling.
