摘要
天龙山石窟作为我国重要的石窟寺文化遗产,受自然营力与人为因素共同作用,已出现不同程度的风化损伤现象。其中SO_(2)和NO_(2)等酸性污染物气体是导致天龙山石窟文物本体劣化的重要因素之一。为系统揭示天龙山石窟砂岩劣化的作用机理与演化规律,本研究针对其砂岩试样开展了SO_(2)-NO_(2)混合气体、相对湿度与降水因素耦合作用下的室内模拟劣化实验。结合无损检测技术与有损检测技术对砂岩的物理、化学性质进行连续检测,并系统分析其组分、结构及性能的演变规律,最终阐明天龙山石窟砂岩在多因素耦合作用下的劣化机理,以期为该石窟的科学认知与预防性保护提供理论支撑。
As an important cultural heritage of grotto temples in China,the Tianlongshan Grottoes have suffered varying degrees of weathering and damage due to the combined effect of natural forces and human factors.Among them,acidic pollutant gases such as SO_(2)and NO_(2)are one of the important factors leading to the deterioration of the Grottoes.To systematically reveal the mechanism and evolution law of sandstone deterioration,this study conducted indoor simulation deterioration experiments on sandstone samples under the effects of SO_(2)-NO_(2)mixed gas,relative humidity and precipitation factors.By integrating non-destructive testing technology with destructive testing technology,the physical and chemical properties of sandstone were continuously detected,and the evolution laws of its components,structure and performance were systematically analyzed.Ultimately,the deterioration mechanism of the sandstone here under the combined action of multiple factors was clarified,with the aim of providing theoretical support for the scientific understanding and preventive protection of the grottoes.
