铁路是我国交通体系的重要组成部分,铁路隧道是铁路工程的重要组成部分,其质量检测工作是隧道工程质量控制的重要环节。因此对于铁路隧道的建设至关重要,应引起相关工作者的重视。目前针对隧道衬砌检测,地质雷达是一种非常有效的监测手段,可以实现快速、连续、无损的检测,并以实时成像方式显示结构剖面。通过实例具体介绍了地质雷达在铁路隧道衬砌质量检测中的应用,以供铁路隧道检测作为参考。 The railway is an important part of China’s transportation system. The railway tunnel is an important part of the railway project. The quality inspection of the railway tunnel is an important part of the quality control of the tunnel project. Therefore, it is very important for the construction of railway tunnels and should attract the attention of relevant workers. At present, for the tunnel lining detection, GPR is a very effective monitoring method, which can achieve fast, continuous and non-destructive detection and display the structural section with real-time imaging. The application of GPR in the lining quality inspection of railway tunnels is introduced in detail through examples, which is taken as reference for railway tunnel inspection.
