探地雷达在隧道检测中的常见问题解析

Tunnel Detection of Ground Penetrating Radar Image Analysis

隧道施工完成后用常规方法很难对仰拱及衬砌质量做出系统评价,地质雷达利用超高频脉冲电磁波探测目标介质的介电常数,很容易掌握仰拱隧底及二衬的地质情况,为工程技术评价提供依据。而对实测的地质雷达图像进行正确解释,是整个工作的重中之重,笔者从理论和实践出发,对几种常见地质雷达检测所出现的问题进行了解析。

Tunnel construction is completed by conventional methods is difficult to invert and the lining to make the system of quality assessment, ground penetrating radar to detect the use of ultra--high frequency electromagnetic pulse target medium dielectric constant, it is easy to master and two at the end of the tunnel invert lining of geological conditions, provide the basis for the engineering technology assessment. While the measured correct interpretation of GPR images, it is the most important task, the author starting from the theory and practice, for some common ground penetrating radar detection of the problems were resolved.
