下沉式火车站交通枢纽规划设计——以嘉兴站为例

Planning and Design of Transport Hub of Sinking Railway Station-Taking Jiaxing Station as an Example

研究目的:许多位于中心城区的铁路客站亟需升级改造,为克服用地紧张的矛盾,一种新的铁路客站——下沉式火车站应运而生。国内对此尚缺乏相关研究,本文力求通过嘉兴站枢纽设计中取得的经验和体会,为今后下沉式火车站的交通规划设计提供借鉴。研究结论:(1)站房下沉能把站前地面空间还给市民,有利于提升区域整体形象,改善换乘条件,并实现人车分离;(2)落客层位宜选择在旅客进站的下一层,有利于远端车库、商业的布置,可以带动地下空间综合开发利用;(3)枢纽的进出口应便于各个方向的车辆快捷进出,减少地面道路交通压力;可以采取地下环路或地下匝道的方式,实现过进车辆的分离;(4)下进下出的交通组织,导致进出站步行流线难以分离,标识指引设置复杂,与常规不同的落客及换乘方式,对后期的运营管理提出了更高的要求;(5)本文研究对中心城区铁路客站改造方案的确定具有参考和借鉴意义。

Research purposes:Many railway passenger stations located in the central urban area need to be upgraded urgently.In order to overcome the contradiction between food and land,a new kind of railway passenger station-sinking railway station came into being.There is still a lack of relevant research on this aspect in China.This paper seeks to provide reference for the traffic planning and design of the sinking railway station in the future through the experience gained in the design of Jiaxing Station Hub.Research conclusions:(1)The sinking of the station building can return the ground space in front of the station to the citizens,which is conducive to improving the overall image of the area,improving the transfer conditions,and realizing the separation of people and vehicles.(2)The drop-off area should be the next floor of the station,which is conducive to the layout of remote garage and commerce,and can drive the comprehensive development and utilization of underground space.(3)The entrance and exit of the hub shall be convenient for vehicles from all directions to enter and exit quickly and reduce the traffic pressure on the ground roads;the way of underground loop or underground ramp can be adopted to realize the separation of passing vehicles.(4)The traffic organization of"lower in and lower out"makes it difficult to separate the pedestrian flow lines in and out of the station,and the setting of signs and directions is complex.Different from the conventional way of drop-off and transfer,higher requirements are put forward for the later operation management.(5)This paper has reference significance for the determination of the railway station transformation scheme in the central urban area.
