摘　　要：EH-4电磁成像系统是一套双源型电磁法数据自动采集和处理的物探系统,它是CSAMT和MT的结合体。文章主要介绍了EH-4高频大地电磁方法的原理、特点和勘探效果。以EH-4应用于勘察中,成功解译出了隧址区存在的断层破碎带及其他异常地质体的位置,为施工及安全防治工作提供了可靠依据。EH- 4 electromagnetic imaging system is a geophysical exploration system based on automatic data collection and processing with double supply electromagnetic method, which is the integration of CSAMT and MT. This paper mainly introduces the principle, characteristics and exploration effect of EH- 4 high-frequency magnetotelluric method. It successfully interprets the location of fault fractured zone and other abnormal geological body in tunnel site with EH- 4 in exploration, which provides reliable evidence for construction and safety protection.
