In the process of tunnel construction, due to poor construction management, the use of unscientific construction methods and construction technology leads to the problems of insufficient thickness of the primary support and the second lining, hollowing, cavity, insufficient number of undense reinforcement mesh and arch, etc., which brings certain safety hazards to the operation of the tunnel. The use of the GER-10 ground penetrating radar can effectively detect diseases in the lining. The following is the measured data of GER-10 in tunnel lining inspection.
