摘要
为提高在黔东地区勘查地下水的成功率,采用应用广泛、勘查效果良好的高密度电法为钻探工作施工划定靶区。本文以高密度电法在贵州东部地区一个地下水勘查项目为例,通过分析其中三条电阻率反演断面剖面,快速地识别了区内断层及断层破碎带,圈定了富水区,给孔位布设提供了物探支撑。钻孔验证出水量满足预期,证明该方法在该区勘查地下水行之有效,能够为该区寻找地下水提供科学依据。
In order to improve the success rate of groundwater exploration in eastern Guizhou,a high-density electrical method,which is widely used and has good exploration effect,is used to delineate target areas for drilling construction.This paper takes a groundwater exploration project in eastern Guizhou by high-density electrical method as an example.By analyzing two resistivity inversion sections,the faults and fault fracture zones in the area are quickly identified,and the water-rich areas are delineated.The layout provides geophysical support.The borehole verified that the water output met expectations,proving that this method is effective in groundwater exploration in this area,and can provide a scientific basis for finding groundwater in this area.
