摘要
为使高速公路养护质量评价结果更全面,运用可拓理论,在补充相关评价指标的基础上,建立高速公路养护质量评价的物元模型,结合层次分析法计算得到随评价指标数值大小而动态变化的权系数,通过确定待评物元关于质量等级j的可拓关联度,得到高速公路养护质量等级,最后以东莞市某高速公路为例,验证了该方法的可行性.结果表明:可拓理论与层次分析法相结合的方法适用于高速公路养护质量评价,其评价结果与实际情况相符.
In order to obtain the more comprehensive results of highway maintenance quality evaluation, this paper, based on the supplementary performance indicators, applies extension theory to establish matter-element model of express way maintenance quality evaluation, and obtains evaluation index values combining with the calculation of Analytic Hierarchy Process, which the coefficients are dynamically changing weighting; besides, grade of highway mainte- nance quality can be obtained by determining the correlation degree of matter-element exten- sion j of the quality grade evaluation; Finally, with the case of the application in a highway of Dongguan city, the feasibility of the method can be proved. This research shows that the extension theory combining with AHP method can be feasible used in evaluation of highway maintenance quality and the evaluation results are consistent with the actual situation.
