苏州轨道交通终点站配线形式研究

Research on the Wiring Form of Suzhou Rail Transit Terminal Station

在我国轨道交通终点站配线形式中,站前折返形式应用较少。文章以苏州在建8号线延伸一站一区间为例,探讨终点站配线形式的比选。苏州8号线延伸线综合考虑设计条件、折返能力、工程经济、可实施性等因素,终点站采用站前交叉渡线折返形式,在满足服务功能的基础上,工程可实施性强,整体效益较好,对国内其他城市延伸段较短的线路有一定的借鉴意义。

In the wiring form of rail transit terminal stations in China,the turn-back form in front of the station is less used.Taking one station and one section on the extension line of Suzhou Line 8under construction as an example,the comparison and selection of terminal station wiring forms are explored.The extension line of Suzhou Line 8 comprehensively considers factors such as design conditions,turn-back capacity,engineering economy,and feasibility,and the terminal station adopts the scissors crossing turn-back form in front of the station.On the basis of satisfying the service function,the engineering has strong feasibility and good overall benefits,which has certain reference significance for lines with short extension section in other cities in China.
