| Abstract: | In the deep survey railway tunnel,the frequency domain electromagnetic has become a reliable geophysical method. EH-4 system is a frequency domain electromagnetic sounding system,which combined the controlled source with the natural source. With engineering practices,the fault,the karst and other geological problems of the tunnel are shown with the successful interpretation. Therefore,it can provide an effective method of investigation for complex deep mountain tunnel inspection. |
