| Abstract: | Each of such bodies as tunnel lining, road way and road surface floorslab has only one inspection face, and the shock echo method has become a new technique for detecting thickness and defects. The general and unique characteristics of the shock echo method and the foundation pile reflection method reveal the mechanism of the reflection technique as well as the different requirements of frequency domain and time domain for impulse. With Huygens-Fresnel belt, the authors have analyzed the horizontal resolution ratio, and pointed out the technological crux of such a method. |
| Keywords: | shock echo thickness detection impulse wave |
