摘要
首先介绍了常用图像法在探地雷达隧道检测中的应用,接着采用小波分析方法提取空洞位置的典型波形,计算出衬砌的厚度与空洞的大小,然后与实际取芯相对比,显示误差在允许的范围内。说明采用小波分析提取探地雷达回波信号具有可行性。
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.
