| 摘 要： | 基于三角模糊数判断矩阵的模糊层次分析法，提出利用模糊数比较大小原理，获得确定元素的权重值，较好解决了三角模糊数无法获得确定元素权重值的问题。并以福州市鼓山大桥悬索桥为工程背号，利用三角模糊数模糊层次分析法建立该桥状态评估指标体系模型，确定评估指标的权重及最终的状态评估值。该评估方法简单易行，精度较高，可以为大跨度悬索桥的养护管理及健康状态预警提供科学依据。

| Abstract: | To determine elements weight value of triangular fuzzy numbers, fuzzy number size com- parison principle was employed to obtain the weight of triangular fuzzy number via fuzzy analytic hi- erarchy process based on the judgment matrix. Exemplified by the construction condition of Fuzhou Gushan mountain suspension bridge, the fuzzy hierarchy process was employed to establish the bridge state evaluation index system model to determine the weights of evaluation indexes and the fi- nal state evaluation value. The results show that the evaluation method is simple with high precision and can contribute to large-span suspension bridge maintenance management and health warning. |
