基于多级可拓的砖木结构古建筑安全性评价

Safety Evaluation of Ancient Masonry-timber Buildings Based on Multilevel Extension

为了科学合理地对砖木结构古建筑的安全性进行评价,针对砖木结构古建筑评价内容的综合性和结构构造的复杂性提出了基于多级可拓理论的安全性评价方法。在物元可拓理论的基础上,建立包含地基基础、上部承重结构及围护结构等3个方面的砖木结构古建筑安全评价体系。运用层次分析法确定各级评价指标的权重,在此基础上通过多级可拓评价法分别对3个层次的评价指标进行多级评价。并将此评价模型应用到广福寺安全性评价中,以此来验证该模型的科学性与合理性。

In order to scientifically evaluate the safety of ancient masonry-timber buildings, this study proposed a safety evaluation method based on multilevel extension theory for comprehensive evaluating the content and the complex structure of ancient masonry-timber buildings. On the basis of the matter-element extension theory, a safety evaluation system of ancient buildings, including foundation, bearing superstructure and enclosure, was established. The weight of the evaluation index was determined by the analytic hierarchy process. On this basis, the multilevel evaluation method was used to the safety evaluation of Guangfu Temple to verify the rationality of the model.
