历次地震表明,大量的砖石古建筑在地震中遭受到了严重的破坏,对破损的古建筑进行合理的评价对古建筑的加固方案的选择起到了重要的作用;现阶段对震后古建筑的破损状态评价方法往往采取了单一指标的判定,为了提高震后砖石古建筑损坏状态评价的准确性,应用集对分析理论与方法,以地表变形的倾斜变形、水平变形与结构的最大层间位移角为评价因子,建立了损坏评价的集对分析模型,提出了基于集对分析理论的震后砖石古建筑损坏评价方法。该方法将各待评定的样本值与分级标准形成对子,逐个比较其共有特性、相反特性及差异特性,从不同侧面刻画2个集合的联系与关系,从而较为准确的评价震后古建筑的破坏状态。并对经历地震破坏的古建筑进行分析,验证该方法的合理性与科学性。
The previous earthquakes showed that a large number of ancient masonry buildings were severely damaged in the earthquake and that the rational evaluation of the damaged ancient buildings played an important role in the selection of the reinforcement plan of ancient buildings. In order to improve the accuracy of damage assessment of ancient masonry buildings after earthquake, the set theory and method are applied to analyze the damage status of the masonry building. Taking the slope deformation of the surface deformation, the horizontal deformation and the maximum floor of the structure The displacement angle is the evaluation factor, the set pair analysis model of damage evaluation is established, and the damage evaluation method of masonry ancient building after earthquake is proposed based on set pair analysis theory. In this method, the sample values to be evaluated and the grading standards form a pair, comparing their common characteristics, opposite characteristics and difference characteristics one by one, and characterizing the relationship and relationship between the two sets from different sides, Disrupt state. The ancient buildings undergoing earthquake damage were analyzed to verify the rationality and scientificity of the method.
