层次分析法在桥面沥青铺装层养护决策中的应用

Application of AHP on Bridge Asphalt Pavement's Maintenance Decision

针对桥面沥青铺装层预防性养护措施,文章总结了影响养护决策的主要因素,建立了三级评价指标体系的层次分析模型。通过判断矩阵和指标权重的综合排序,给出层次分析评价过程和方案优选的决策方法。研究结果表明,AHP法可作为桥面沥青铺装层预防性养护方案优选重要依据。

Aiming at the preventive conservation measure of bridge floor bitumen paving,this paper summarizes the main factors influencing the maintenance decision and establishes a three-level hierarchical analysis model for evaluation system and the index.Through the judgment matrix and the comprehensive ranking of indexes weight,the assessment processes for the hierarchical analysis and decision-making methods for optimum scheme are set up.AHP has theoretical guidance and practical application value which can be used as important basis of preventive maintenance scheme selection for the asphalt pavement on bridge deck,and the result is objective.
