| 摘 要： | 为了确保大跨度斜拉桥的安全运营,保证桥梁的使用寿命,采用不确定型层次分析法对桥梁的状态进行评估.介绍了不确定型层次分析法的相关理论和应用对象,在众多计算区间数判断矩阵的方法中,经过对比分析选用了最优传递矩阵理论,因为其计算结果精确可靠.以哈尔滨松花江斜拉桥为背景桥,利用不确定型层次分析法建立了该桥状态评估的指标体系和评估模型,确定了评估指标的权重并通过计算得到该桥最终的状态评估值,证明了该方法的可行性与实用性.这种评估方法的应用将会为大跨度斜拉桥的养护管理提供更加科学的依据.

| Abstract: | In order to guarantee the safety service and life-span of long-span cable-stayed bridges,the uncertain type of analytic hierarchy process (AHP) method is adopted to access the bridge condition.The correlative theory and applied objects of uncertain type of AHP are introduced,and then the optimal transitive matrix method is chosen to calculate the interval number judgment matrix,which makes the weights of indices more reliable and accurate.Finally,with Harbin Songhua River Cable-Stayed Bridge as an example,an index system and an assessment model are proposed for the condition assessment of this bridge,and by using uncertain type of AHP,the weights of assessment indices are fixed and the final assessment results of the bridge are calculated,which proves the feasibility and practicability of this method.The application of this assessment method can provide the scientific basis for maintenance and management of long-span cable-stayed bridges. |
