摘要
研究目的:广州南沙港铁路是一条接轨于广珠铁路鹤山站,终到广州南沙港区的货运铁路,由于沿线既有及规划高速公路、既有及在建铁路、高压走廊、厂矿企业、城市既有布局及规划和通航河道等控制因素遍布,对铁路线路方案的可行性造成了重大影响,严重阻碍了项目建设推进。本文旨在结合广州南沙港铁路生产实际,通过展开线路方案选线设计研究,合理绕避或处理沿线控制因素,确保铁路线路方案的可行性和合理性,大力推动项目建设进程,并为类似项目建设提供宝贵经验。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,须综合考虑工程投资、工程实施难度、工程风险和地方政府意见等影响因素,以确保选定的线路方案最优;(2)层次分析方法和多目标决策模型可有效辅助线路方案比选的决策;(3)本文基于广州南沙港铁路的线路方案选线设计研究比较全面地探讨了线路方案比选思路和方法,具备典型的科学合理性,可供类似项目借鉴应用。
Research purposes： Guangzhou Nansha port railway is a freight railway which start from Heshan Railway Station of Guangzhou - Zhuhai railway and end of the Guangzhou Nansha port. Because the control factors such as existing and planned expressway, existing and in the construction of the railway, high - voltage wire corridor, factories and mines, both the layout and planning of city, navigable river and so on spread all over the railway which has caused a great influence on the feasibility of railway line scheme and has seriously hindered construction progress of the project. This paper attempts to combine the construction reality of Guangzhou Nansha port railway by expanding the route scheme of route design and reasonably avoiding or treating along the control factors that in order to ensure the feasibility and rationality of the railway line scheme and vigorously promote the process of project construction and provides valuable experience for the construction of similar projects. 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 must synthetically considering the influencing factors such as project investment, difficulty of project implementation, project risk and local government opinion and so on in order to make sure the selected line scheme optimal. （2） The analytic hierarchy process and multi - objective decision - making model can effectively assist making decision for comparison and selection of route scheme. （3） In this paper, the study on the design of line selection of route scheme basing on Guangzhou Nansha port railway has comprehensively discusses the ideas and methods of comparison and selection of route scheme that has the typical scientific rationality and could provide reference and application for similar program.
