【摘要】 为了解决日益突出的在役桥梁结构健康评定问题,提出了受损桥梁结构健康等级的多级模糊综合评判 方法.建立了桥梁健康评判模型,确定了各层次论域子集中的影响因素,并通过对桥梁部件和桥梁结构体系2 个级别健康状况的模糊综合评判来确定在役桥梁的健康等级.这种评定方法较好地适应了桥梁健康影响因素 的复杂性和模糊性.实例分析对此进行了很好的验证.更多还原

【Abstract】 This paper discusses questions on structural health evaluation of bridge on service. A model of health evaluation of bridge is set up. Influene effects of bridge health were analyzed. Based on service conditions of the bridge and results of expert investigation, weights and evaluation matrixes are put forward. Furthermore, method of multi-phase fuzzy comprehensive evaluation is given for appraising damaged bridge structure, which establishes the foundation of health evaluation of bridge on service. An example shown that this method is well fit to characteristics of questions on structural health evaluation of bridge structure.更多还原
