| 摘 要： | 为了准确地对在役双曲拱桥的耐久性进行评估,应用层次分析法建立了双曲拱桥耐久性评估的模型,应用模糊数学中隶属函数理论,对评估模型中的两个层次中的评估指标建立隶属函数,采用二级模糊综合评判进行耐久性评估。通过工程实例分析表明,评估结果与实际情况较为吻合,该方法是可行的,具有较好的工程实用性。

| Abstract: | For the sake of accurately evaluating durability for double arch bridge,the evaluation model for the durability of existing double arch bridges was established by Analytical Hierarchy Process（AHP）.Using the membership functions theory in fuzzy mathematic,membership functions was established for evaluating indicators in two levels of the evaluation model and durability was evaluated by two level fuzzy overall evaluation models.Project cases show that： the evaluation results are identical with actual conditions.Thus,this method is feasible and has great project practicality. |
