Application of Ground Penetrating Radar for Quality Detection of Tunnel Lining
The Golmud-Lhasa section of Qinghai-Tibet railway is located in the plateau and permafrost region which tunnel lining produces serious diseases in the extremely bad environment. This paper states the application of Ground Penetrating Radar (GPR) for quality detection of tunnel lining and how to choose parameters, sit detection lines, analyze GPR cross section and classify lining diseases in filed investigation. The results suggest that non-destructive testing technology of GPR can be used to detect the tunnel lining diseases mainly including second lining thickness, cavities and backfilling imperfection zones, and the technology is effectively to detect tunnel lining in abominable surroundings. Furthermore, detection results can provide scientific basis to evaluate the tunnel’s safety performance and diseases degree objectively.
