城市轨道交通折返线型式比较研究

为研究不同车站折返线配线型式,满足折返能力和折返功能,减少车站规模和造价,以南昌地铁3号线银三角北站为背景,分析和研究站前折返和站后折返的折返间隔和适用条件,得出不同条件下推荐的折返配线型式。对于线路的永久起、终点站,从节能投资、减少车站规模和提高折返能力的角度,优先采用站前折返的方式;对于线路的临时起、终点站,需要结合远期延伸线路长度、车站型式、车场选址和全线配线综合确定;对于中间站,一般设置单渡线起临时折返功能,或者与停车线一起设置贯通式双停车折返线。

Comparative Study on Types of Return Lines of UrbanRail Transit

In order to study the configuration of return lines indifferent stations to meet the return capacity and function, and reduce thescale and cost of the station, the return interval and applicable conditions ofthe return ahead of and behind the station are analyzed by taking YinsanjiaoNorth Station on Nanchang Metro Line No. 3 for example. And then therecommended wiring types under different conditions are obtained. For thepermanent starting and terminal stations of the line, the return ahead ofstation is recommended considering cost and station scale reduction and returncapacity improvement; for the temporary starting and terminal stations of the line,the long term extension line length, station type, yard location and thewhole line wiring should be considered; and for the intermediate stations, thefunction of single crossover is generally set for temporary return, or doubleparking return line together with the parking line is set.
