摘　　要：为了充分考虑多种评估参数以提高混凝土火灾损伤评估的准确性,应用可拓学理论和方法,将混凝土火灾损伤分级标准、评价指标及其特征值作为物元,对评价标准及实测数据进行归一化后,得到模型的经典域、节域、权系数及关联度,进而建立了混凝土火灾损伤评价的物元模型,并予以应用分析。结果表明,该方法是一种较为简单实用的混凝土火灾损伤综合评价新方法。In order to consider the diversity of evaluation factors, the theory and method of extenics were applied to evaluate the degree of fire-damage concrete.The grades of fire-damage concrete, the evaluating indexes and its eigenvalue were made as matter element, after normalizing the evaluation standard and surveyed data, the sutra field, controlled field, weight coefficient and relating degree were obtained, meanwhile, the model for comprehensive evaluating the degree of fire-damage concrete was built up,then this model was applied to some example,the result showed that it was a simple and practical method for evaluating the degree of fire-damage concrete.
