摘要
提出了文物保护工程中确定壁画地杖层空腔区域的一种新方法--声波检测方法。该方法是以人工激振的方法向介质发射声波,在一定的空间距离上接收介质物理特性调制的声波,通过观测和分析声波在不同介质中的传播速度,可以确定地杖层的空腔区域。从而为壁画文物保护工程的设计提供可靠的地质资料。因此,该方法具有一定的使用价值。
A new method-acoustic detection is put forward in confirming the detachment area of mud plasters in the protection project of the historic relics. Through launching sound wave to medium with manual shaken method, and receiving the modulated sound wave including its physical characteristic at a distance, we can confirm the detachment area of mud plasters after observing and analysing the speed among different medium. Thereby, we offer the reliable geological information for protecting the murals. So, this method has its certain effect.
