| Abstract: | In view of the shortage of water damage detection method in the current tunnel advance prediction，the transient electromagnetic fine detection method for tunnel water damage detection was studied.The fine detection method mainly includes the fine field construction method of tunnel ahead detection，the fine processing method of transient electromagnetic data and the fine processing method，the problems that need to be paid attention to in the thinning detection are also introduced.Through the study of the field construction method and data fine processing method of tunnel transient electromagnetic refinement，a complete set of transient electromagnetic detection techniques suitable for tunnel detection was summarized.Through the application in Sichuan，Guizhou，Yunnan and other places，it was proved that the tunnel transient electromagnetic fine detection method is accurate and effective to the anomaly detection，and can be an effective means to detect water damage in tunnel geological prediction. |
