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 prospecting method based on the magnetotelluric theory. It has a good indication of the relatively low resistivity zones such as underground karst caves and water-rich layers. Take the Railway Bridge and Tunnel Survey as an Example to Introduce the Practical Application of the System in Engineering Geological Exploration.
