| 摘 要： | 介绍了EH4电导率成像系统在探测地下异常体的工作原理和测试方法。先对碳酸盐岩区的已知地质异常体进行EH4探测试验,总结其剖面布置、异常扩展效应和点距选取的规律,确定工作参数,并将试验取得的经验和参数应用到后续在该区开展的乐滩水库引水灌区工程TBM施工隧洞六浪出口段岩溶特征探测工作,并分析其应用效果。

| Abstract: | An introduction was made on the operating principle and testing method of EH4 conductivity imaging system used for survey of underground anomalies. Testing survey of EH4 was conducted first with known geological anomalies in carbonate area. The rules of profile arrangement, anomaly spreading effects and receiving space were summarized, and the working parameters were determined. Experience and parameters out of test were applied in karst survey for the Liulang outlet section of TBM construction tunnel of Letan Reservoir irrigation project. |
