电法勘探在抗旱找水工程中的应用

扫码查看
电法勘探是物探技术的一个分支,以不同岩、矿石间的电性差异为基础,通过观测和研究天然电磁场和人工电磁场的空间与时间分布规律进行地质勘查.地下岩石的电阻率受含水率的影响较为明显,因此电法勘探广泛应用于抗旱找水工程.通过实例讲述如何利用电法勘探判断物探异常区、划分潜力含水区,可供工程技术人员参考.
Application of Electrical Exploration in Drought Resistance and Water Finding Engineering
Electrical exploration is a branch of geophysical technology that is based on the differences in electrical properties between different rocks and ores.It is a geological exploration method that observes and studies the spatial and temporal distribution patterns of natural and artificial electromagnetic fields.The electrical resistivity of underground rocks is significantly affected by water content,therefore,electrical exploration is widely used in drought resistant water finding projects.This article uses examples to illustrate how to use electrical exploration to determine geophysical anomaly areas and divide potential water bearing areas,which can be used as a reference for engineering and technical personnel.
