奉国寺泥塑X射线照相检测及初步研究

X-radiographic study of Liao Dynasty clay sculptures in Fengguo Temple,Liaoning Province

辽宁省义县奉国寺是我国现存三大辽代寺院之一,其大雄殿内的彩绘泥塑群是辽代泥塑的代表,具有一千多年的历史。目前,这批泥塑出现了倾斜、泥层开裂、木骨架外露等问题,亟待保护修复。本研究通过X射线照相检测,获得了泥塑的内部结构、病害发育和修复痕迹等信息,这些信息对于泥塑的保护修复工作具有重要的参考价值。另外,还对比了胶片成像和计算机X射线成像系统成像两种方式的优缺点,讨论了泥塑X射线照相检测影响因素,研究结果对于其他文物的X射线照相检测具有一定参考价值。

Fengguo Temple in Yixian County,Liaoning Province is one of the three existing Liao Dynasty temples in China.The painted clay sculpture group in the Great Buddha’s Hall is a representative of Liao Dynasty clay sculptures,and boasts a history of more than one thousand years.At present,these sculptures have such problems as tilting,cracking of the mud layer and exposure of the wooden skeleton,which urgently need conservation and restoration.In this study,the non-destructive method of X-radiography was taken to investigate the internal structures,disease development and repair traces of these clay sculptures.The results provide a considerable reference for the future preservation work.In addition,the advantages and disadvantages of X-ray film imaging and computed radiography are compared,and the influencing factors of clay sculpture X-radiography are discussed,which have certain reference value for the applications of X-radiography to other cultural relics.
