[摘要]我國許多珍貴石刻文物均采用紅砂巖雕刻,但是由于保護措施不到位,導致風化嚴重。為了更好的保護紅砂巖石刻,基于各國學者的現有研究,本文對紅砂巖風化的機理進行歸納整理,主要包含干濕交替機理、有機酸腐蝕機理、凍融循環機理、生物作用機理和外部表層剝落機理等。隨后,針對紅砂巖風化的特點,基于鑒定和加固兩個方面對現有方法做提煉。綜述是同濟石刻修復的準備工作的一部分。

Abstract: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 of two aspects. This review is a part of work for “Tongji” carving’s rehabilitation.

Keywords: red sandstone;weathering;weathering mechanism;stone monument protection
