摘　　要：EH4电磁成像系统是一种以大地电磁理论为基础的物探勘查手段,对于地下岩溶洞穴及富水层等相对低阻区都有较好的指示作用。以铁道桥隧勘查为实例介绍该系统在工程地质勘探中的实际应用。The EH4 electromagnetic imaging system is a geophysical exploration method which is based on the magnetotelluric theory, which is good for underground karst cave and low resistivity zones in water--rich layer. Taking the railway tunnel and bridge detection for an example, this paper introduces the application of EH4 electric conductivity imaging system to the engineering geological detection.

关 键 词：EH4电磁成像系统 铁路隧道与桥梁 工程物探 低阻区
