为了客观、系统地评估桥梁安全状况,提出三标度层次分析法与模糊综合评判的集成评估方法。首先,运用层次分析法分析影响桥梁安全状况的评估指标,进而建立桥梁安全评估的目标层、准则层、指标层,并形成桥梁安全评估指标体系。采用三标度层次分析法计算评估指标权重。其次,通过模糊综合评判模型,对桥梁安全评估体系进行分层次模糊综合评估。结合模糊加权平均算子和模糊综合评判最大隶属度原则,确定桥梁安全状况分值,参照评语集得出桥梁安全等级。最后,将该集成评估方法应用到江坡头大桥工程实例中,评估结果与现行规范一致,体现了该方法的可行性与实用性。

In order to have an objective and systematical evaluation of bridge safety and keep the bridge working well , a comprehensive integrated assessment method based on three-scale analytic hierarchy process and fuzzy eval-uation model was presented .On the basis of the method , the application research of bridge safety assessment was principally illustrated as follows .Firstly, the assessment indexes of bridge safety were determined through the anal-ysis of various factors that had effects on safety operation of bridges by analytic hierarchy process .The assessment index system for bridge safety w...
