中文摘要：针对传统方法子指标的不确定性问题,提出了一种基于三角直觉模糊网络分析法(triangular intuitionistic fuzzy analytic network process,TIFANP)、优劣解距离法(technique for order preference by similarity to an ideal so-lution,TOPSIS)和三角直觉模糊综合评价(triangular intuitionistic fuzzy comprehensive evaluation,TIFCE)的大跨桥梁安全状态评估方法.首先,建立大跨桥梁安全状态分层指标体系,采用 TIFANP 法确定考虑指标相互影响后的权重;其次,引入TOPSIS法分配指标各截面权重,进而获得子指标取值;然后,将桥梁安全状态划分为 5 级,通过TIFCE法构建指标在不同等级的隶属度和非隶属度函数,据此建立对应判断矩阵,并进行桥梁安全状态指数综合计算;最后,以某大跨悬索桥监测数据为依托,验证了所提方法的有效性.结果表明:所提方法能够更合理地处理评价指标间的相互影响以及专家评分时的不确定,可为运营期大跨桥梁安全状态的准确评估提供新思路.

外文标题：Safety State Assessment Method of Long-Span Bridges Based on TIFANP-TOPSIS-TIFCE Method

外文摘要：Aiming at the problem of uncertainty of sub-indicators in traditional methods,a safety state assessment method for long-span bridges was proposed,which was based on triangular intuitionistic fuzzy analytic network process(TIFANP),technique for order preference by similarity to an ideal solution(TOPSIS)and triangular intu-itionistic fuzzy comprehensive evaluation(TIFCE).Firstly,the hierarchical indicator system for the safety state of long-span bridges was established,and the TIFANP method was used to determine the weights of the indicators af-ter considering their mutual influence.Subsequently,the TOPSIS method was introduced to allocate the weights of each section of the indicators,thereby obtaining the values of sub-indicators.Then,the safety state of the bridge was divided into 5 levels,and the membership and non-membership functions of the indicators at different levels were constructed by the TIFCE method.On this basis,the corresponding judgment matrices were established,and the comprehensive calculation of the bridge safety state indicators was carried out.Finally,the effectiveness of the pro-posed method was verified by the monitoring data from a certain long-span suspension bridge.The results show that the proposed method can deal with the interactions between the evaluation indicators and the uncertainty of the ex-perts'scoring in a more reasonable way,which can provide a new idea for the accurate assessment of the safety state of long-span bridges during the operation period.
