Non-destructive Testing And The Application Research On Concrete Constructure Of Tunnels

The procession of the tunnel concrete testing was from devastating-testing to non-destructive testing. With the application of the high frequency electromagnetic wave, more and more people turned to study the non-destructive testing technology. The GPR way was a new technology with the development of high frequency electromagnetic wave used in the non-destructive testing. The GPR way is more portability, faster, more accuracy and straighter than the other testing way. The study of the GPR technology should be great foreground in future.The auther has learnt a great deal of data about tunnel testing and GPR., and studied the theory of the non-destructive testing to tunnel lining. The aulfaer structured the Geophisics model and used the computer language flexiblely to programe the GPR signal, the Synthetic GPR record and the deviding GPR file.The article based on the theory and combined the real project and model experimentation tightly, and summarized the rule of the bug in the tunnel lining, and put forward a rational intepreted model. It should be useful to the non-destructive testing.
