摘要

环氧树脂是古建筑木构件修复加固的常用材料，为了科学合理地使用环氧树脂，基于多准则决策理论建立古建筑木构件修复加固用环氧树脂性能评价模型。参考古建筑木构件修复加固工程对环氧树脂的要求与相关标准确定环氧树脂的性能指标集合，采用熵权法与层次分析法分别得到各性能指标客观权重与主观权重，综合主客观权重对各性能指标赋权，使用优序法与逼近理想解排序法（technique for order preference similar to an ideal solution，TOPSIS法）结合各性能指标复合权重构建两种综合性能评价模型。通过验证试验对十组环氧树脂进行综合性能评价，结果表明复合加权TOPSIS综合性能评价模型更全面客观，更适用于古建筑木构件修复加固用环氧树脂，可作为选择和使用环氧树脂的参考方法。

Abstract

Epoxy resin is commonly used for repairing and reinforcing of ancient building timber members. To ensure its scientific and rational application

a performance evaluation model for epoxy resin was established based on multi-criteria decision theory. The evaluation index of the epoxy resin set was determined based on the requirements and relevant standards for repairing and reinforcing wooden components in ancient architecture. The entropy weight method and the analytic hierarchy process were used to obtain each property index's objective weight and subjective weight respectively. The subjective and objective weights were used to weight each property index. Combined with the composite weight

the optimal order method and the TOPSIS (technique for order preference similar to an ideal solution) were used to construct two comprehensive evaluation models. Validation experiments were conducted to evaluate the performance of ten groups of epoxy resins. The results show that the composite weighted TOPSIS comprehensive evaluation model is both more comprehensive and objective

making it better suited for the evaluating epoxy resin comprehensively. This model can serve as a reference method for selecting epoxy resin for repairing and reinforcing ancient buildings.
