介绍了地质雷达的工作原理及其在隧道衬砌厚度检测中的原理和技术.结合工程实例,对某隧道右边墙衬砌厚度进行了地质雷达无损检测.对该项地质雷达探测施工中的一些技术问题,如测线布置、数据采集、数据图像处理等进行了详细的介绍.结合检测结果说明了地质雷达在隧道衬砌厚度检测中的优越性,并给出相关的施工建议.%The working principle of Ground Penetrating Radar(GPR) is introduced,in which the principles and techniques in detecting tunnel lining thickness are also proposed. Combined with the engineering practice, the GPR nondestructive testing is conducted in a tunnel wall thickness of the right side. Meanwhile ,some technical problems in GPR detection, such as measuring line layout, data acquisition, data image processing etc, is de-tailedly introduced. Based on the measuring results, it indicates the superiority of Ground Penetrating Radar in detecting thickness of the tunnel lining and puts forward relevant construction proposal.
