地质雷达检测与处治隧道二次衬砌质量研究

Study on Detection and Treatment of Tunnel Secondary Lining Quality by Ground Penetrating Radar

介绍地质雷达在隧道二次衬砌检测中的基本原理,并结合工程案例,简要介绍地质雷达二衬质量检测的数据采集、处理、解译的基本流程;针对二衬中出现的脱空、不密实、厚度不足等质量问题,分析产生的原因并提出相应的处治措施。

This paper introduces the basic principle of ground penetrating radar (GPR) in the detection of secondary lining of tunnels.Combining with engineering cases,it briefly introduces the basic flow of data acquisition,processing and interpretation of the quality detection of secondary lining of GPR.Aiming at the quality problems of void,non-compactness and insufficient thickness in secondary lining,the causes are analyzed and the corresponding treatment measures are put forward.
