摘　　要：冲击反射法是一种新型的混凝土结构无破损检测技术。它可以用专门的冲击器在结构物的一面轻微弹击 ,利用应力波的往复反射探测结构物内部的缺陷和厚度。作者研究了这项技术并推出一整套测试系统。本文叙述该项技术的原理。Impact-echo method is an innovative NDT of concrete structure. While flicking gently on the surface of structure using special impactor, the internal defects and thickness of structure can be detected by receiving the response of stress waves. The technique was studied by authors and a set of testing system (IES-A) was developed successfully. The principle of the technique, the testing system and its application on project are recounted in this paper.
