| 摘 要： | 桥梁技术状态评估是一个涉及大量主观性的不精确的数据和专家知识的复杂过程.为提高评估过程的有效性和客观性,提出了一个基于灰色关联度和变权理论的评估方法,用于在役双曲拱桥耐久性技术状态评估.总结了影响混凝土双曲拱桥耐久性的因素,考虑双曲拱桥的构造特点,应用层次分析法建立了评估在役双曲拱桥耐久性的多层次模型,应用灰色关联系数评估其耐久性技术状况.工程实例说明该方法,计算过程简单,便于工程实际应用.

| Abstract: | Bridge durability evaluation is a complex process involving large amount of data and expertise which are usually imprecise and subjective.For the improvement of the effectiveness and objectivity of the evaluation process,this paper proposed a new method based on grey relation analysis and variable weight method.Influence factors for two-way curved arch bridge durability were summarized,and then a multi-level evaluation model was established with the AHP methods,and the constitution characteristics of two-wa... |
