无损检测在晋祠圣母殿彩塑保护中的应用

Application of Non-destructive Testing in the Protection of Sculptures of the Notre Dame Temple in Jinci Temple

此次无损检测是以太原市晋祠博物馆圣母殿内的40余尊宋代彩绘泥塑为检测对象,用数字化技术采集和处理得到残损部位的图像和数据,对残损状况进行量化、描述和编辑,对彩塑进行裂缝分类、破损分类、彩绘剥落层分类,形成量化损伤指标,便于评价和保护。中国是一个多地震国家,由地震造成文物古迹的破坏比比皆是,采用脉动法对彩塑进行动力测试,得到每尊彩塑的动力参数,就可以针对需保护的古代彩塑,采取有效的"抗震"措施加以保护。

Non-destructive inspections were performed in this study for 40 color-painted clay sculptures originally built during Song Dynasty. Images and data were obtained using digital sampling technique and processing. Their damage states were quantified, described and archived with classification of cracks, classification of damage and defects, classification of layer peeling, and the proposal of quantified damage index, which are useful for the assessment and protection of these color-painted clay sculptures. China is a seismic-prone country and there are many cases of damaged cultural relics and historic sites by earthquakes. This study used pulsing and single pulse method to measure the dynamic response of color-painted clay sculptures, and obtained the dynamic parameters for each of them. The proposed method can be used to protect these color-painted clay sculptures efficiently against potential earthquakes.
