基于模糊综合评价法的高速公路路线方案比选研究

Study on Comparison And Selection of Expressway Route Plan Based on Fuzzy Comprehensive Evaluation Method

为了提高公路项目的社会效益、增强对公路沿线地区的服务功能、降低项目总投资额度,本文以广东省某高速公路为工程依托,基于模糊综合评价法建立高速公路路线总和评价指标体系,从社会效益、生态和谐、技术设计及美观舒适等多个视角对该高速公路的三条路线方案进行定量分析,得出该高速公路各路线方案的功能评价分数,并进一步得到最优线路设计方案。

In order to improve the social benefit of highway project,strengthen the service function along the area along the highway and reduce the total amount of project investment,this paper,based on a certain expressway in Guangdong Province, establishes the total evaluation index system of highway route based on fuzzy comprehensive evaluation method,from social benefit,ecological harmony,technical design and beauty. A quantitative analysis of the three route plans of the expressway is carried out by a number of perspectives,such as view comfort,and the function evaluation scores of each route plan of the expressway are obtained,and the optimal route design scheme is further obtained.
