摘　　要：隧道衬砌、路道、路面楼板等只有一个检测面 ,冲击回波法成为新的厚度及缺陷检测方法。由冲击回波法与基桩反射法的共性及特性揭示了这种方法的机理及频域与时域检测 2种不同施测方法以及对激振的不同要求。用惠更斯菲涅尔带分析了水平分辨率 ,最后说明该种方法的技术关键。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.
