高等级公路改扩建线形指标适应度评价

Sufficiency Appraisement of Reconstructed High-Grade Highway′s Alignment Indexes

采用基于层次分析法的模糊评价方法,通过建立公路升级改造项目线形指标适应度评价体系,合理确定各评价要素的权重,对升级改造的公路的线形指标适应度进行评价,从而为确定公路升级改造形式提供设计上的理论依据。结合洛栾高速洛阳至嵩县段工程可行性研究工程实例,证明该方法科学、实用。

The article uses the fuzzy evaluation method based on AHP to establish alignment indexes sufficiency appraisement system of highway reconstruction projects,determines the weight of each appraisement factor,and then evaluates the sufficiency of alignment indexes of reconstructed highway,which provides theory basis for highway reconstruction design.The method is proved to be scientific and practical through the feasibility study of Luoyang-Luanchuan Expressway Luoyang-Songxian Section.
