针对当前隧道超前预报中水害探测使用方法的不足,研究出基于隧道水害探测的瞬变电磁精细化探测方法,该方法主要包括隧道超前探测的精细化现场施工方法和瞬变电磁数据的精细化处理方法,并包括在精细化探测中需要注意的问题。通过对隧道瞬变电磁精细化现场施工方法和数据精细化处理方法的研究,总结出适合隧道超前探测的瞬变电磁探测成套技术。瞬变电磁精细探测方法在四川、贵州、云南等地的应用证明,该方法能准确有效地对异常区进行探测,成为隧道地质预报中探测水害的有效手段。
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.
