【摘要】：作为公路勘测设计中需要解决的重要问题，高速公路路线方案综合比选，是公路建设前期决定全局的重要工作。路线方案合理与否，直接关系到项目的地位功能、回收效益、运输效率等预期效果的发挥，对项目建成后能否满足国家政治、经济建设需要也具有举足轻重的作用。在高速公路路线方案优选过程中，涉及经济、社会、环境等各方面诸多因素，情况较为复杂，一套科学合理的优选评价指标及决策评价方法就显得尤为重要。因此，研究选取合理的评价指标以及科学可靠的综合比选方法，以在高速公路建设初期选取总体效果最优且可行性最好的路线方案，具有重要意义。本文在阐述高速公路选线的概念、分析高速公路选线的控制因素及基本原则的基础上，结合高速公路选线的系统特点，基于全面性与重要性相结合、定性指标与定量指标相结合等指标体系的设置原则，从多层次结构出发，在高速公路路线方案影响指标全面系统分析的基础上，综合经济、技术、社会、环境和安全的等方面，构建了全面、系统、综合的多因素、多层次的高速公路路线方案评价指标体系。然后，遵循路线方案评价的基本原理，紧扣路线方案优选的基本原则，结合路线方案评价的特点及一般要求与程序，在综述常用路线方案评价方法的基础上，综合考虑路线方案评价过程及结果的客观性，探索提出了基于改进熵权TOPSIS的高速公路路线方案评价方法，建立了高速公路路线方案评价的数学模型，并基于MATLAB软件平台编制了相应的计算机程序。接着，分析了高速公路选线的步骤及方法，并以福建省永安至武平高速公路为载体，在收集全面的指标数据的基础上，对提出的高速公路路线方案评价指标体系及评价方法进行实例分析。通过实例分析，从3个备选路线方案中综合比选出最优方案，验证了本所构建评价指标体系的实用性和所建立评价模型的可操作性。最后，回顾前面的相关研究和实例分析，总结了本文的主要成果与结论以及可以进一步研究的问题，并对高速公路路线方案综合比选方法的发展前景进行了放眼展望。
[Abstract]:As an important problem to be solved in highway survey and design, the comprehensive comparison and selection of highway route scheme is an important work that determines the overall situation in the early stage of highway construction. Whether the route scheme is reasonable or not is directly related to the status function and recovery benefit of the project. The expected effect of transportation efficiency plays an important role in meeting the needs of national politics and economic construction after the project is completed. In the process of highway route scheme optimization, it involves economy and society. Many factors, such as environment and so on, are more complicated, so a set of scientific and reasonable evaluation index and decision evaluation method are very important. Therefore, it is very important to study and select reasonable evaluation index and scientific and reliable comprehensive selection method. It is of great significance to select the route scheme with the best overall effect and the best feasibility in the early stage of highway construction. On the basis of expounding the concept of expressway route selection, analyzing the control factors and basic principles of expressway route selection, combined with the systematic characteristics of expressway route selection, this paper combines comprehensiveness with importance. The setting principles of the index system, such as the combination of qualitative and quantitative indicators, from the perspective of multi-level structure, on the basis of comprehensive and systematic analysis of the impact indicators of expressway route schemes, and integrating economic, technical, social, environmental and safety aspects, A comprehensive, systematic, comprehensive multi-factor and multi-level evaluation index system of expressway route scheme is constructed. Then, following the basic principle of route scheme evaluation, following the basic principle of route scheme optimization, combining the characteristics and general requirements and procedures of route scheme evaluation, the paper summarizes the common route scheme evaluation methods. Considering the objectivity of the evaluation process and result of the route scheme, the evaluation method of the expressway route scheme based on the improved entropy weight TOPSIS is proposed, and the mathematical model of the expressway route scheme evaluation is established. And based on the MATLAB software platform, the corresponding computer program is compiled. Then, the paper analyzes the steps and methods of highway route selection, and takes Yongan to Wuping Expressway in Fujian Province as the carrier, on the basis of collecting comprehensive index data, The evaluation index system and evaluation method of expressway route scheme are analyzed by examples. Through the example analysis, the optimal scheme is selected from the comprehensive ratio of three alternative route schemes. The practicability of the evaluation index system and the maneuverability of the evaluation model are verified. Finally, this paper reviews the previous research and case analysis, summarizes the main achievements and conclusions of this paper, as well as the problems that can be further studied, and looks forward to the development prospects of the comprehensive comparison and selection method of expressway route scheme.
