城市轨道交通小型停车场出入线接轨方式

Inbound and Outbound Siding Track Joint Scheme of Small Parking Yard in Urban Rail Transit

针对目前城市轨道交通出入线接轨方式存在的问题,以武汉地铁12号线复兴村小型停车场工程为依托,对复兴村站单线折返入库接轨、黄海路站单线接轨、复兴村站和黄海路站八字形接轨3种出入线接轨方案进行了对比,建议采用单线折返入库接轨方案。对推荐方案出入线的平面及纵断面进行了设计,并对出入线收发车能力进行了论证,其结果满足12号线远期高峰小时行车量的要求。该出入线接轨方式解决了停车场紧邻正线布置时接轨难的问题,显著节省了工程投资。

Aiming at the problems existing in the inbound-outbound siding track joint scheme of urban rail transit and based on the Fuxingcun small parking yard project of Wuhan Metro Line 12,this paper compared the three inboundoutbound siding track joint schemes including Fuxingcun Station single siding track joint scheme for turn-back into the garage,Huanghai Road Station single siding track joint scheme and the splayed track joint scheme of Fuxingcun Station and Huanghai Road Station,and the single siding track joint scheme for turn-back into the garage was suggested. The plane and vertical section of the recommended scheme inbound-outbound siding were designed,and the receiving and departing capacity of the inbound-outbound siding was demonstrated,the result of which could meet the requirement of the long-term peak hour traffic volume of Line 12. This inbound-outbound siding track joint scheme solves track joint difficulty of parking yard adjacent to the main line,and saves the project investment significantly.
