基于层次分析法的高等级公路路面性能影响因素评价

Evaluation of Influencing Factors of High-grade Highway Pavement Performance Based on Analytic Hierarchy Process

为科学准确地分析高速公路沥青路面使用性能的影响因素,保证高速公路的高效营运和科学养护。本文依托实际工况,详细分析了实际交通量、路面结构与材料、路面养护历史、温湿度状况及线形指标等因素对高等级公路路面性能的影响,然后基于层次分析法(AHP),将路面使用性能影响因素作为目标层建立层次结构,进行各影响因素的敏感性分析,最终得到高等级公路路面性能的影响因素敏感性排序,对高速公路科学养护决策具有重要指导意义。

In order to analyze the factors affecting the performance of highway asphalt pavement scientifically and accurately and ensure the efficient operation and scientific maintenance of the highway,this paper analyzes the effects of actual traffic volume,pavement structure and materials,pavement maintenance history,temperature and humidity conditions,and alignment indicators on the pavement performance of high-grade highways in detail,based on actual working conditions.The performance influencing factors are used as the target layer to establish a hierarchical structure,sensitivity analysis of each influencing factor is conducted,and finally the sensitivity ranking of the influencing factors of high-grade highway pavement performance is obtained,which has important guiding significance for scientific highway maintenance decision-making.
