基于AHP法的行车冲切道路面层水毁评价模型及应用

Evaluation model and application of water damage of road surface by driving punching based on AHP method

针对沥青路面水毁影响因素复杂、多层次的特点,考虑行车冲切作用对路面的损伤,基于AHP法的基本原理,建立了以道路条件、交通情况、气象条件为第一层因素,道路分类等为第二层因素的行车冲切道路面层水毁层次结构。借鉴模糊数学基本思想,建立了各因素评价标准,水毁强度指数与道路面层水毁等级的对应关系,并构建了行车冲切道路面层水毁评价模型和实现流程。通过对高新区纵五路某路段水毁路面的实地调查,将该评价模型加以应用,评价结果显示该路段为“中等水毁”。本文所构建评价模型优化了道路面层的水毁评价方式,可为项目的施工及养护管理提供技术支撑和建议。

In view of the complex and multi—level characteristics of influencing factors of asphalt pavement water damage,considering the damage to the pavement caused by driving punching,based on the basic principle of AHP method,a hierarchical structure of driving punching pavement water damage is established,with road conditions,traffic conditions and meteorological conditions as the first layer factors and road classification as the second layer factors.Using the basic idea of fuzzy mathematics for reference,the evaluation criteria of various factors,the corresponding relationship between the water damage intensity index and the water damage grade of road surface are established,and the evaluation model and implementation process of water damage of road surface cut by vehicles are constructed.Through the field investigation of a section of Zongwu Road in High tech Zone,the evaluation model is applied,and the evaluation results show that the section is“moderately damaged by water”.The evaluation model established in this paper optimizes the water damage evaluation method of road surface,which can provide technical support and suggestions for project construction and maintenance management.
