摘要 研究目的: 高速铁路建设飞速发展,铁路选线方案众多,影响铁路选线的因素较多,如工程地质条件复杂、工程投资巨大等。传统线路方案比选一般将经济指标作为衡量线路选线的主要影响因素。本文依托南深高速铁路项目,认真分析影响线路选线的多种主要因素,并基于层次分析法建立南深高速铁路选线的决策指标体系,充分考虑多种因素对决策层的影响,建立基于层次分析法的高速铁路线路选线的决策模型。
研究结论: (1)线路方案比选是铁路选线设计研究的重要内容,进行线路方案比选时,需综合考虑工程投资、工程实施难度、工程风险等影响因素,以便得出最优的线路方案;(2)运用层次分析法推荐结论与南深高速铁路线路方案比选推荐方案一致;(3)基于层次分析法的高速铁路选线模型可以弥补一般高速铁路选线的主观性、单一性缺点,同时表明该决策模型具有较强的实用性、合理性和科学性,可为类似工程项目选线提供一定的参考和借鉴价值。

Abstract：Research purposes: With the rapid development of high-speed railway construction, there are many schemes about route selection of railway and many factors affecting route selection of railway, such as complicated engineering geological conditions and huge investment. The traditional route selection comparison generally takes the economic index as the main influence factor to measure the route selection. This paper analyzes the main factors that affect the route selection based on the Nanning-Shenzhen high-speed railway project, established the index system of decision-making for the route selection of Nanning-Shenzhen high-speed railway based on analytic hierarchy process, and considering the influence of many factors on the decision-making level, establishes the decision-making model of the route selection of high-speed railway based on analytic hierarchy process (AHP).
Research conclusions: (1) Comparison and selection of route scheme is an important content of design of railway line selection.When we conduct the comparison and selection of route scheme, the influencing factors such as project investment,difficulty of project implementation, and project risk should be considered synthetically in order to make sure the selected line scheme optimal.(2) The recommended conclusion of using analytic hierarchy process is the same as the route selection recommended scheme of Nanning-Shenzhen high-speed railway. (3) The route selection model of high-speed railway based on analytic hierarchy process can make up for the shortcomings of subjectivity and singleness in general route selection of high-speed railway, and the decision-making model is practical, reasonable and scientific. This paper can provide reference for the route selection of similar projects.
