摘要
我国许多珍贵石刻文物均采用红砂岩雕刻,但是由于保护措施不到位,导致风化严重。为了更好的保护红砂岩石刻,基于各国学者的现有研究,本文对红砂岩风化的机理进行归纳整理,主要包含干湿交替机理、有机酸腐蚀机理、冻融循环机理、生物作用机理和外部表层剥落机理等。随后,针对红砂岩风化的特点,基于鉴定和加固两个方面对现有方法做提炼。综述是"同济"石刻修复的准备工作的一部分。
Many precious stone carvings in China are carved in red sandstone. However, due to inadequate protection measures, they are seriously weathered. In order to better protect the red sandstone carvings, based on the existing research of scholars from various countries, this paper summarizes the weathering mechanism of red sandstone, which mainly includes: dry wet cycle mechanism, organic acid corrosion mechanism, freeze-thaw cycle mechanism, biological action mechanism, and external surface peeling mechanism, etc. Subsequently, in view of the characteristics of the weathering of red sandstone, the existing methods are refined based on the identification and reinforcement. This review is a part of work for “Tongji” carving’s rehabilitation.
