摘要
研究目的:设计方案比选是一个多目标、多因素、多层次的系统工程。因引入新增线路,结合预测运量,既有线路的通过能力远期已趋于饱和,需进行各方案的优缺点分析,并合理选择引入方案。本文通过菏兰铁路引入兰考南站方案研究,选择合理的引入方案,确定合理的线路走向,达到降低工程难度和节省投资的目的。研究结论:(1)本文通过对运输组织、技术经济、车站咽喉疏解近期工程、同步实施线下工程、已实施工程等诸多方面的研究,结合河南省最新城际铁路网规划,分析各方案的优缺点,确定出相对优化的推荐方案,即上下行联络线分别在东西咽喉疏解方案;(2)通过运营条件、线路长度、工程投资等诸多方面的分析,结合沿线村镇分布、联络线设置条件等因素,对引入兰考南站线路方案进行了研究,推荐东绕仪封乡以R=3 000 m限速引入兰考南站方案;(3)本文研究可为类似项目的方案比选奠定理论基础,具有一定的参考价值。
Research purposes:The optimal selection of variant design scheme is a multi-level system with multi-objective and multi-factor.Considering the introduction of new lines,according to the predicted traffic volume,the carrying capacity of existing lines has become saturated in the long term.Therefore,the advantages and disadvantages of each scheme were analyzed and the introduction scheme was reasonably selected.This paper studied the scheme research on the introducing Heze-Lankao railway to Lankao south station,selected the introduction scheme,and determined the most reasonable route to reduce the difficulty and investment of the project.Research conclusions:(1)This paper analyzed the advantages and disadvantages of each scheme and determined a relatively optimized recommendation scheme through the research on transportation organization,technology and economy,recent works of station throat relief,synchronous implementation of offline projects,implemented projects and many other aspects,combined with the latest intercity railway network planning in Henan Province.(2)Based on the analysis of operation conditions,line length,investment and many other aspects and the distribution of villages and towns along the line,the line scheme of introducing Lankao South Station was studied.(3)The method presents a theoretical foundation for the similar project and has certain reference value.
