摘要
洞窟、造像等大型石质文物大多开凿在露天岩体崖壁上,风化病害是这类石质文物的主要病害之一,已经影响到了文物的传承。因此,开展石质文物风化分级的研究对于制定相应的保护措施具有重要的现实意义。目前,对石质文物风化的形态、机理、影响因素的研究较多,也取得了一些成果,但大多是依据对文物外观和岩体的某项指标进行风化分级,缺乏全面性。本文从岩体外观、岩体结构和岩体物理力学性质三方面出发建立了石质文物风化分级的指标体系,通过结合前人的研究成果并进行现场的实验研究,建立了风化等级的分级标准,将层次分析法与模糊数学理论结合起来,提出了一套兼顾岩体文物特性和工程特性的石质文物岩体风化分级方法。论文进一步将这套方法应用于太原晋阳大佛岩体风化分级研究,对于大佛边坡岩体的风化程度进行了评判,为大佛的重修提供了重要的依据。
Large scale lithic cultural relics such as grottos and stone sculptures, mostly carved on rock cliff and standing in the open air for many years, are suffering from serious weathering diseases so that their existence is badly threatened. Therefore, it is significant to study the weathering classification of lithic cultural relics for their protection. So far, there have been many studies about the types and mechanisms as well as influence factors of wealhering diseases of lithie cultural relies, and some useful results have been obtained. Many of them, however, focus on some individual factors such as appearance profiles or rock property parameters of lithic cultural relics, and are not integrated enough. In this paper, an evaluation index system is established based on eolligating factors from appearance and rock mass integrality as well as physical and mechanical properties of lithic cultural relics, and weathering classification criteria of lithie cultural relics based on this index system are sealed according to the study results so far and the test results of this work. Furthermore, this study suggests a set of procedures for weathering classification of lithic cultural relics, colligating cultural relic peculiarity and engineering property of lithic cultural relics, and combining fuzzy mathematic method and analytic hierarchy process （AHP）. Finally, the weathering state of the rock mass of Jinyang Grand Buddha in Taiyuan, China is evaluated by means of this method, which provides some lines of evidence for the repairing of the Jin- yang Grand Buddha.
