Study on Application of GPR to Quality Detection of Tunnel Lining
Ground penetrating radar (GPR) is a real-time, non-destructive testing technique using high frequency radio waves that can yield data with very high spatial resolution and the data can be acquired rapidly. It uses high frequency radio waves to inspect the interior of concrete structures and is widely used for tunnel construction due to its fastness, accuracy, continuity etc.. The paper takes a tunnel as an example, systematically introduced the work principles of GPR and elaborates on the successful application of GPR to quality detection of the tunnel lining. To mainly analyze the quality of tunnel lining such as lining thickness, non compact, cavity, crack etc.. It is important to eliminate the hidden dangers during the tunnel operation, and also give experiences and references for the quality detection of the similar tunnel construction.
