| Abstract: | Transient electromagnetic method(TEM)is a time domain electromagnetic induction method.In this paper,based on the fault in the middle of Yushe tunnel of Liuwei high speed in Guizhou Province,the application of TEM in the detection of fault water in the tunnel is studied.The detection principle of TEM and the engineering survey of the supporting point are introduced,and the experience of TEM in the detection of fault water in the tunnel is summarized.The application of the method and the results shows the superiority of TEM in the geophysical exploration of water bearing fault in deep tunnel,and the detection results of TEM are basically consistent with the stratigraphic correlation revealed by tunnel excavation. |
