| Abstract: | The application of image method in tunnel inspection with ground penetrating radar was introduced firstly; then typical waveform of the hole location was extracted by wavelet analysis method. After calculating the thickness of lining and the size of hole, and comparing with the actual core sample, it was showed that the error was within allowable range. The result proves that extracting ground penetrating radar echo signal by wavelet analysis is feasible. |
