摘　　要：现存古建筑大多带伤服役,体内残损状态复杂多样,且对古建筑进行的加固维修与原有残损对结构本体的安全性能影响截然相反。为实现对古建筑的预防性保护,需要量化古建筑纯木结构中的残损状态及修缮措施对其安全状态的影响。基于山西万荣飞云楼各构件残损状态普查统计数据,结合现有规范及工程经验对构件残损状态等级详细划分,建立4级模糊层次分析模型,确定结构体中承重构件及构件残损类型的权重值及判断矩阵,通过模糊层次分析方法对飞云楼进行安全状态评估。结果表明,建立的模糊层次安全评价模型能反映残损状态及修缮措施对飞云楼安全状态的影响,有效将结构评价与构件评价联系起来,验证了修缮措施能有效增强古建筑结构本体的安全性及稳定性,该模型及方法可以应用到多层古建木结构的安全等级评价中。Most of the existing ancient buildings are in service with injuries,and the internal damage state is complex and diverse.Meanwhile,the reinforcement and maintenance of the ancient buildings carried out by the later generations and the original damage have the opposite impact on the safety performance of the original structure.In order to realize the preventive protection of ancient buildings,it is necessary to quantify the impact of damaged state and repair measures of pure wooden structures on the safety state of ancient buildings.Based on the statistical data of the damaged state of various components of Feiyun Wood Pavilion in Wanrong,Shanxi Province,and combined with existing norms and engineering experience,this paper divides the damaged state of components in detail,establishes a four-level fuzzy hierarchical analysis model,and determines the weight value and judgment matrix of the load-bearing components and the damage types of components in the structure.The security state of Feiyun Wood Pavilion is evaluated by fuzzy analytical hierarchical approach.The results show that the fuzzy analytical hierarchy safety evaluation model established can reflect the damage state and theimpact of repair measures on the safety state of Feiyun Wood Pavilion, effectively link structural evaluation withthe component evaluation, and verify that the repair measures can effectively enhance the safety and stability ofthe ancient building structure. The model and method can be applied to the safety grade evaluation of multistoreyancient wooden structures.
