Abstract
Recently, as tunnel structure is getting old, many deformations and defects have been occurred. As tunnel hasthe cause of deformation is very difficult. Then, itis necessary to investigate the state of tunnel lining and to e stimate the deformation cause and safety for tunnel.In this study, inspection and diagnosis system for effective ma destructive techniques such as GPR (ground penetrating radar), impact echo test, and infrared thermal techniqueswere applied to tunnel lining inspection. Tunnel lining analysi s system was developed to analyze the stability ofo find the probable causes and indicate themethod for repair and reinforcement for tunnel.
