摘要
冲击回波法是一种有效的检测混凝土结构的无损检测方法,通过试验验证,它不仅可准确测量混凝土结构的厚度,也可确定混凝土结构内部的各种缺陷,如表面开口裂缝、空洞及蜂窝等。实用性较强,检测精度较高。成像软件的使用使缺陷的辨别更加直观、简便。
The impact-echo method is an effective nondestructive testing method for concrete structures. The experimental result showed that the method could not only accurately determine the thickness of the concrete slabs, but also successfully locate various flaws in concrete, such as vertical surface-opening cracks, voids, honeycombing, and so on. The method had good practicability and inspection precision. The defect distinguish could be more direct and simpler by the imaging software.
