基于模糊层次分析的连续梁桥健康状态的评估

摘要

以模糊层次分析法为基础,通过桥梁健康状态评估的隶属度函数和桥梁技术状态评估等级之间的量化关系,建立桥梁健康状态评估模型,利用计算的各因素隶属度值和权重的结果,获得各层次的模糊评价集.根据最大隶属度原则来评估桥梁结构对应的技术状态等级,用其结果来指导桥梁的维修养护决策.%Based on fuzzy analytic hierarchy process, The model of bridge health state estimation is established using the quantification relations between the bridge technical state estimation grade and degree of membership function of bridge health estimation, making use of the computed result of various index of degree of membership value and weight, obtains all levels of fuzzy estimation collection. According to the maximum membership principles to evaluate the technical state grade of bridge structure the corresponding level, and with its result to instruct the decision-making of bridge maintenance and strengthening.
