定县汉简的分析检测与保护修复研究

Research on Analysis and Restoration of Dingxian Bamboo Slips

河北定县八角廊40号汉墓早年遭遇盗焚,墓内汉简的性状、形貌特征、物理性能发生改变,且致使竹简字迹辨认困难,严重地影响了其文献文物价值。通过对定县炭化汉简的微观形貌、力学性能分析检测并进行相关实验,基本可以了解汉简热解炭化的过程、内部形态结构的变化及收缩特征,确定有效荷载范围以及复形方法。在遵循文物保护基本原则的前提下,编制了《河北定县汉简保护修复方案》,并对汉简开展了清洗、复形、封护等保护修复工作,使汉简的形貌得到一定程度的恢复,物理强度得到增强。定县汉简的保护修复弥补了国内炭化竹简保护修复工作的技术空白,为相似文物的保护修复与研究提供了重要借鉴。

Han tomb No.40 found at Bajiaolang in Dingxian County,Hebei Province was robbed and burned years ago.As a result,the placement,morphological characteristics,and physical properties of the bamboo slips in the tomb were changed,the writing on slips was difficult to identify,which seriously reduced their historical value.Through the analysis and testing of the microstructure and mechanical properties of carbonized Han bamboo slips from Dingxian County,the process of pyrolysis and carbonization of the slips,the change of internal morphological structure,and the shrinkage characteristics can be understood.Furthermore,the effective load range of the slips and the reshaping processes were also determined.Following the basic principles of cultural relics protection,the "Protection and Restoration Scheme of Han Bamboo Slips in Dingxian County,Hebei Province" was compiled,and the protection and restoration work including cleaning,reshaping,and sealing of Han bamboo slips was carried out,so that the morphology of the bamboo slips was restored to a certain extent and the physical strength was enhanced.The protection and restoration work on the Dingxian Han bamboo slips has filled a gap in the protection and restoration technology of carbonized bamboo slips in China and serves as an important reference for the protection,restoration,and research of similar cultural relics.
