基于运营经验的地铁配线设置研究

Metro Auxiliary Line Setting Based on Operation Experience

结合长沙地铁的设计、运营经验,阐述了单渡线、停车线、车辆基地出入线的设置思路。提出地铁配线设置不仅应满足规范要求,更应满足运营的需求。对于单渡线的设置,建议适当调整间距,缩减车站规模;对于停车线的设置,建议尽可能考虑临时折返交路设置的可能性,其使用效率还有待验证;车辆基地出入线应尽可能兼做折返功能,同时不宜过长,采用八字型出入线与正线接轨时,运营效率更高,还.能实现列车调头。

Considering the operation and design experience of Changsha Metro,the setting of single crossing line,parking line,depot entry/exit line is expounded.The metro auxiliary lines should meet not only regulation requirements,but also the operation demands.The setting of single crossing line is suggested to adjust the spacing distance and to reduce the station scale.The setting of parking line is suggested to consider the possible temporary turn-back and crossing set-up,while the u-tilization rate requires further verification.The depot entry/exit line should accommodate the turn-back function as well,with minimum length.By adopting Chinese-eight-shaped connection between entry/exit line and main line,the operation becomes more efficient while allowing train U-turn.
