基于多条城市轨道交通与规划铁路枢纽站衔接的线站位研究

对于引入多条城市轨道交通的规划铁路枢纽站而言,研究综合换乘功能最优的线站位方案是两者衔接的前提和关键。分析城市轨道交通线路与铁路枢纽站间常见的2种线站位关系和5种衔接方式,以引入4条城市轨道交通的规划重庆东站为案例,基于其枢纽定位、周边规划及现状、线网规划及换乘需求,研究多条城市轨道交通与规划铁路枢纽站衔接的线站位方案。结果表明,两者的衔接应首先考虑换乘便捷,流线组织简单;其次考虑尽量减少对周边建筑物的影响。多条城市轨道交通同时引入时,考虑将与国铁换乘需求较大的线路车站置于国铁站房下方,以缩减与国铁换乘走行距离,同时尽量避免国铁站房下方只设置一条城市轨道交通,以更快疏散国铁突发客流,便于客流组织。然后将其余线路车站置于广场下方,以解决周边城市客流需求。

Research on Line and Station Location Based on Connection of Multiple Urban Rail Transits with Planned Railway Hub Station

For planned railway hub station in connection with multiple urban rail transits, it is of premise and key to study the optimal locations of the line and station with comprehensive transfer function. This paper analyses the common two kinds of line-station relationship and five connection modes between urban rail transit and railway hub station with reference to the planned Chongqing East Railway Station in connection with four urban rail transit lines. Based on the hub location, surrounding planning and current situation, network planning and transfer demand, the line and station location schemes for the connection of multiple urban rail transits with planned railway hub station are studied. The results show that the connection should consider the convenience of transfer and the simplicity of streamline organization firstly, and then take into account minimizing the impact on the surrounding buildings. When several urban rail transits are introduced, the stations of the urban rail transit with larger transfer demand should be placed under the railway station buildings so as to reduce the transfer distance to the railway. Meanwhile, single urban rail transit line should be avoided under the railway station buildings in order that the sudden increased passenger flow of the railway could be evacuated quickly to facilitate passenger flow organization. Then the other stations of the urban rail transits are placed under the square to meet the surrounding urban passenger demand.
