基于AHP-TOPSIS的山区低等级公路路面破损评价方法

Evaluation method of low-grade highway pavement damage in mountainous area based on AHP-TOPSIS

以山区低等级公路路面为研究对象,依据不同种类路面的破损危害性不同,拟在公路路面评价中提出路面破损指数概念,对山区低等级公路路面破损程度进行综合评价。所用模型是利用层次分析法(AHP)对不同种类的路面损毁危害性进行赋权,并利用逼近理想解排序法(TOPSIS)计算山区低等级公路路面破损程度与最优情况的贴近度,进而将山区低等级公路路面破损情况转化成区间为[0,1]的路面破损指数,其中路面破损指数越大表示路面的破损程度越高。此模型方法简单,能够运用少量数据对山区低等级公路路面的破损程度进行定量评价,可为山区公路的养护工作提供更准确的数据参照。

In this paper,the pavement of low-grade highway in mountainous areas is taken as the research object.According to the different harmfulness of different kinds of pavement damage,the concept of pavement damage index is proposed in the evaluation of pavement,so as to comprehensively evaluate the pavement damage degree of low-grade highway in mountainous areas.The model used in this paper uses Analytic Hierarchy Process(AHP)to weight the harmfulness of different types of pavement damage and Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS)is used to calculate the closeness between pavement damage degree and optimal condition,which then converts the pavement damage of low-grade highway in mountainous areas into the pavement damage index with a range from 0 to 1,is the higher the index of pavement damage,the higher the degree of it.This model is simple and can quantitatively evaluate the pavement damage degree of low-grade highway in mountainous area with a small amount of data,which can provide more accurate reference for the maintenance of highway in mountainous areas.
