综合物探方法在福建永泰清凉地下水勘查中的应用

Application of Comprehensive Geophysical Exploration Method in Qingliang Groundwater Exploration in Yongtai County,Fujian Province

为克服单一物探方法的局限性,减少“多解性”,在地下水勘查中需要采用综合物探方法,多种方法相互验证、取长补短。在永泰清凉地下水勘查中提出了首先投入快速、低价的面积性高精度磁测工作,推断出断裂构造的大致位置;而后在断裂构造有利位置投入有限的联合电剖面法、CSAMT等电法工作,确定断裂构造的产状、埋深等;最后布设钻孔进行验证的工作方案,取得较好的地质效果。

In order to overcome the limitation of single geophysical exploration method and reduce the"multi-solution",comprehensive geophysical exploration method should be adopted in groundwater exploration.Multiple approaches to mutual verification and complement each other.Based on the application effect of comprehensive geophysical exploration method in Qingliang groundwater exploration,the approximate location of fault structure is inferred by using rapid and low price area high precision magnetic survey.And then the joint electric section method and CSAMT method are put into the favorable position of fault structure to determine the occurrence and buried depth of fault structure.Final set up boreholes to verify,and obtain better geological effect.
