桥梁耐久性评估方法的研究

摘要

本文应用模糊关系合成原理,从多个影响因素对桥梁耐久性的隶属等级进行综合评估.根据我国现行规范和标准采用五种评价等级以评估桥梁耐久性状况.在对模糊综合评价的处理上采用非对称贴近度法.最后,通过工程实例对该方法的实用性进行了论证.%This paper uses the fuzzy relation synthesis principle to overall evaluate the membership grade of bridge durability from multiple influence factors. It adopts five estimation scales to evaluate bridge durability condition according to our country,s current criterion and standard. On the processing of fuzzy comprehensive evaluation it uses non-symmetric similarity scale method. At last, it demonstrates the practical applicability of the method by engineering example.
