灰色关联分析与变权综合法在桥梁评估中的应用

引用灰色关联分析和变权综合的概念，提出用AHP方法（层次分析法，analytic hierarchy process)建立评价指标体系后，量化并确定评价指标评语和其它层次指标评语的综合方法，并以实例计算分析，结果表明，灰色关联度概念和变权综合方法可较好地应用于大型桥梁结构的状态评估。

Degree of Grey Incidence and Variable Weight Synthesizing Applied in Bridge Assessment

A synthetic method for assessing the condition of long span bridges is proposed in this paper by applying the degree of grey incidence conception and variable weight synthesizing theory.The basis of this method is to set up an assessing index system based on AHP(analytic hierarchy process),as well as to get the comment of assessing indexes through proper quantification.The examples show that the proposed method is reliable and relatively accurate,and can be easily used in the bridge condition assessment.
