基于AHP-熵值法的桥面层间综合工况分级研究

Research on Working Condition Grading of Deck Interlayer Based on AHP-Entropy Method

介绍了AHP-熵值法优化模型:针对中国路面层间处治标准的不足,通过ANSYS软件分析了铺装层厚度、铺装层模量、纵坡度、曲线半径、跨径、超载及温度7个因素下的桥面层间最大剪应力规律,得出不同工况的单因素分级;通过AHP熵值法模型确定了不同工况的优化权重,并结合单因素分级的结果进行赋值,最后对桥面层间进行综合工况分级,为层间处治提供了依据。

Optimization model based on AHP-Entropy method was introduced.Aimed at the insufficiency of Chinese standards of interlayer treatment,the law of maximum shearing strength at deck interlayer affected by factors including the pavement thickness,pavement modulus,longitudinal grade,curve radius,span,overload and temperature was analyzed,and factor grading of different working conditions was obtained.The optimization weight of different working conditions was determined by the AHP-Entropy model,and the results were assigned in combination with the factor grading.The working condition grading of deck interlayer was carried out,which provides interlayer treatment with basis.
