摘　　要：以桥梁结构及各构部件的状态作为评价对象,基于模糊理论建立以隶属度为评价指标的底层函数,并通过BWM(best worst method)法为层级权重评价手段对模型进行了综合评估;采用自下而上,逐级传递的方法,将底层向量与各层级按BWM法确定的指标权重相结合,并对各级指标展开逐层评价,最终确定了桥梁的综合评定等级;根据综合评定等级对桥梁各部位加固的优先顺序进行判断;最后以丁家桥为实例进行了该桥梁的综合状态评估,并给出了加固优先等级的建议。Taking the state of the bridge structure and its various parts as the evaluation object,a low-level function with membership degree as the evaluation index was established based on fuzzy theory,and the model was comprehensively evaluated by using the BWM(best worst method)method as a hierarchical weight evaluation means.Using a bottom-up and step-by-step transmission method,the bottom level vector was combined with the indicator weights determined by the BWM method at each level,and the indicators at each level were evaluated layer by layer.Finally,the comprehensive evaluation level of the bridge was determined.According to the comprehensive evaluation level,the priority order of reinforcement for each part of the bridge was determined.Finally,a comprehensive state evaluation of Dingjia Bridge was conducted as an example,and suggestions for reinforcement priority order were given.
