城市轨道交通车站折返能力计算

Turning-back Capacity Calculation of Urban Mass Transit Station

针对城市轨道交通折返站的通过能力,对站前折返和站后折返方式分别进行特点分析和能力计算。在具体分析计算和总结各种列车折返方式优缺点的基础上,提出采用现代化电气及信号设备,采用大号码道岔,缩短站前制动点至道岔的距离,压缩列车停站时间等提高城市轨道交通车站折返能力的措施。

Targeting with the passing capacity of turning-back station of urban mass transit, this paper analyzes characteristics of the turning-back mode before civil works and after civil works respectively, and calculates the corresponding capacity. On the basis of analyzing the advantages and disadvantages of each train turning-back mode, the paper puts forward suggestions on improving turning capacity of urban mass transit station, such as applying modern electric and signaling equipment, as well as large number turnout, short- ening the distance between braking point in front of station and turnout, and shortening the train detention time at station.
