Abstract: For problems of 1-9 scale in the Analytical Hierarchy Process ( AHP) ,exponential scale and corresponding indicator of random consistency test were employed to evaluate bridge technology condition based on the Weber-Fechner's Law. Taking concrete filled steel tubular( CFST) arch bridge as an example,weight of each component could be calculated after judging matrix of exponential scale and 1-9 scale based on the same importance to relations. Calculation results indicated that exponential scale could accurately reflect the relationship among components of CFST arch bridge.

Key words: Analytical Hierarchy Process ( AHP) , Weber-Fechner's Law, exponential scale, CFST arch bridge, weight

摘要: 针对层次分析法中1-9标度存在的问题,根据心理学上韦伯-费希纳定律,引入指数标度及对应的随机一 致性检验指标,应用到桥梁技术状况评定中。以钢管混凝土拱桥为例,依据相同的重要性关系评语,分别以指数标 度和1-9标度构造判断矩阵,计算出各个构件权重系数。计算结果表明:指数标度能较为准确地反映出钢管混凝 土拱桥构件之间的重要性关系。
