该文通过实例介绍了探地雷达检测隧道衬砌的典型图像,分析了目前检测中存在的主要问题,提出了 应搞清物探方法中的几个概念;监测者不仅需要一定的物探知识,还需要学习和掌握隧道设计、施工的知识, 并熟悉有关规范,才能避免作出与规范和隧道的基本常识相悖的检测结论。 In this paper, a typical example of GPR tunnel lining detection is introduced by example. The main problems in current detection are analyzed. Several concepts in geophysical prospecting method are proposed. The monitor not only needs certain geophysical knowledge, but also needs Studying and mastering the knowledge of tunnel design and construction and being familiar with the relevant norms can avoid the detection conclusion that is contrary to the norms and basic common sense of the tunnel.
