摘要
EH4电磁法是大地电磁测深技术之一,它利用天然或人工电磁场的测量,求取地下介质电阻率的分布规律,进而达到解决工程建设中的有关问题,如在断层破碎带探测等工程地质问题中,取得了良好的应用效果。介绍EH4电磁测深技术的基本原理、测试技术、资料处理和成果分析等,给出了EH4电磁测深法在断层勘察中的一个实例并总结该方法的几个探测优势。
EH4 electromagnetic method is one technique of magnetotelluric（MT） system,it uses measuring both of natural and man-made eleetromagnetie signals to obtain the regularity of distribution of eleetrieal resistivity of the earth beneath,and then solving the problems in engineering construction, it has been widely and effectively applied in many fields, such as measuring fracture zone etc. in engineering geology. The paper introduces the basal principle, measuring technique,data processing and result analysis of EH4 electromagnetic sounding,meanwhile,it provides an example about faults investigating, summarizes several advantages of EH4 electromagnetic sounding.
