冲击回波在混凝土无损检测中的应用

Application of the ballistic echo in the nondestructive examination of concrete

探讨了冲击回波法的基本原理,运用冲击回波法对L型钢筋混凝土柱厚度、荷载作用下开口裂缝深度进行了检测,试验结果表明,冲击回波在检测混凝土结构厚度和确定开口裂缝深度方面是一种快速、有效的无损检测方法,更符合工程结构检测的实际情况。

It discusses the basic principle of the ballistic echo, and does examination to the L-reinforced concrete pile thickness and the open crack depth acted by loading by the ballistic echo. The test shows the ballistic echo is one quick and effective nondestructive examination method in the structural thickness examination and the open crack depth confirmation, which agrees the actual condition of engineering structure examination much more.
