电法勘探在张家口宣化区后备地下水水源地勘查中的应用

Application of electric exploration in reserve groundwater source exploration in Zhangjiakou Xuanhua District

为了解决重点城镇、村庄水资源短缺问题,我国在地下水资源勘查方面投入了大量的人力物力和技术手段,其中地球物理方法在地下水的勘查中起着重要作用。本文论述了电阻率测深和激电测深两种方法在张家口宣化区区后备地下水水源地勘查中的应用,基本查明了该区的地层岩性、富水构造、富水层位空间分布与富水性,为该区后期的钻探工作和水资源评价提供依据[1]。

In order to solve the shortage of water resources in key urben and villages,we have invested a lot of manpower,material resources and technical means the in the exploration of groundwater resources,geophysical method plays an important role in groundwater exploration.In this paper,we discusses the application of resistivity sounding and IP sounding in the exploration of reserve groundwater source in Xuanhua District,Zhangjiakou.The formation lithology,water-rich structure,spatial distribution of water-rich horizon and water-rich water content in this area are basically identified,which provides a basis for the later drilling work and water resources evaluation in this area.
