摘　　要：建筑外墙空鼓是普遍存在的问题,如何检测既有建筑外墙的空鼓情况越来越得到关注。在深入分析传统敲击检测方法的基础上,在不同外墙饰面、多种工况下进行了实验验证,结果表明,可利用墙面敲击声音振动特性判别墙面空鼓情况。It is common to see the external walls of a building become hollowed. As a result, more and more people are interested in how to inspect the hollowing situation. After profoundly analyzed the conventional knocking approach, this article tests such problem in various scenarios in which the external wall finish differs from each other and finally reaches a conclusion that it is feasible to determine the hollowing status of a building＇s external walls via the sound and vibration characteristics of such walls after being knocked.
