枢纽建设中的轨道交通站位选择——以北京地铁6号线西延工程苹果园站为例

Selection of Rail Transit Station in Hub Construction——A Case of Pingguoyuan Station of Metro Line 6 West Extension Project in Beijing

近些年,随着城市轨道交通的快速发展,轨道交通线网的进一步完善,在线路与线路的交点处往往形成非常大的换乘客流节点。由于便利的交通优势,乘客换流节点往往能在该区域形成商业中心。苹果园交通枢纽站是由三条大运量的轨道交通线路(地铁1号线车站、地铁6号线车站、低速磁悬浮S1站)及普通公交、BRT、商业、办公建筑等组合而成的复杂的车站。车站在设计中要考虑复杂的客流流线组织、多样的交通衔接、复杂的工程接口、不稳定的工程建设时序等方面的因素。本文通过对北京地铁6号线西延工程(M6)苹果园站的工程实例分析,揭示大型枢纽站中M6苹果园的站位选择问题,从而得出类似工程中,关于地铁在大型枢纽中的站位设计,为以后的大型枢纽设计提供参考。

In recent years,with the rapid development of urban rail transit and the further improvement of the rail transit network,very large commuting passenger flow nodes are often formed at the intersection of lines.Due to convenient transportation advantages,passenger transfer nodes can often form a commercial center in this area.Pingguoyuan Transportation Hub Station is a complex combination station of three largevolume rail transit lines(Metro Line 1 station,Metro Line 6 station,and low-speed maglev S1 station)and ordinary buses,BRT,commercial and office buildings.In the design of the station,factors such as complex passenger flow line organization,diverse traffic connections,complex engineering interfaces,and unstable engineering construction sequence should be considered.Based on the analysis of the project case of Pingguoyuan station in the West Extension Project of Beijing Metro Line 6,this paper reveals the location selection of M6 station in the largescale hub station,and concludes the station design of the subway in large hub so as to provide a reference for future large hub design.
