常规的水文地质勘察方法以地质参数定量测定为主,影响地质勘察效果。因此,研究大地电磁测深法在水文地质勘察中的应用这一课题。利用大地电磁测深法接收地面电场与磁场信息,确保地质勘察效果。基于大地电磁测深法反演水文地质电性参数,推知水文地质等电性参数,避免水文介质电性对勘察的影响。模拟水文地质勘察均匀半空间静态效应,反映水文地质勘察区域不均匀体的位置深度,满足水文地质勘察需求。采用实例分析,验证该方法的勘察准确性更高,能应用于实际生活中。

The conventional hydrogeological exploration methods mainly focus on quantitative determination of geological parameters,which affects the effectiveness of geological exploration.Therefore,studying the application of magnetotelluric sounding method in hydrogeological exploration is a topic.Using the magnetotelluric sounding method to receive ground electric and magnetic field information,ensuring the effectiveness of geological exploration.Based on the magnetotelluric sounding method,the hydrogeological electrical parameters are inverted,and the hydrogeological electrical parameters are inferred to avoid the influence of the electrical properties of the hydrological medium on the survey.Simulate the static effect of uniform half space in hydrogeological exploration,reflect the depth of uneven bodies in the hydrogeological exploration area,and meet the requirements of hydrogeological exploration.By using case analysis,it is verified that the survey accuracy of this method is higher and can be applied in practical life.
