新建线路与既有线换乘方案研究

On Transfer Plans for New and Existing Subway Lines

随着城市轨道交通快速发展,节点换乘直接关系到整个线网的运行效率,所以,车站的换乘方案是新线建设前期研究的关键。针对新建线路与既有线路换乘需求与修建困难、管理复杂与出行便捷等对立统一的矛盾体,在确保基本功能的基础上,认真分析具体的站址环境和既有站运营条件,提出对通行设施进行改造、扩容,努力创造客流组织可行、换乘便捷、工程可实施的技术方案。最后,对线网规划中不同线路的建设时序,从投资控制、工程可实施性和旅客出行的便捷性等角度,提出了相应的预留换乘节点方式建议。

With the rapid development of urban rail transportation, transfer station layouts plays a critical role in the over- all metro network＇ s operation efficiency. Therefore, transfer stations program is the key to preliminary study of a new sub- way line. This article, in view of some conflicts such as the one between demand for interchange and difficulties in building transfer stations as well as the one between complicated management and passenger convenience, through a careful analysis of the specific environment of the station site and the existing station operating conditions, proposes a technology scheme on the basis of renovation and expansion for the access, that is beneficial to passenger flow organization and is practical in im- plementation. Finally, based on construction sequence of the different lines in the network planning, from the perspective of investment control, engineering implementation and passenger convenience, the paper puts forward some advices on the form of transfer nodes reserved in advance.
