摘　　要：将牵引计算应用于城市轨道交通站后折返站的通过能力计算,并分析其计算效果.首先阐述并分析了站后折返的种类及其作业流程,得出了单线折返与双线折返最小发车间隔的计算公式.同时提出了当咽喉区不能并行作业时车站折返线数目的合理设置建议;接着通过引入动力学方程,给出了基于牵引计算求解站后折返能力的计算方法.最后采用建设中的北京地铁北京西站作为算例车站、DKZ4型列车作为算例列车,求出了列车在节能与节时两种不同操控模式下的站后折返最小发车间隔,单线与双线折返时间相差明显.在此基础上与均加减速节时模式下的各项计算结果进行了对比分析,各项指标差别明显,说明了在折返计算中采用牵引计算求解结果更准确.Method of train traction calculation is applied urban rail transit, and the calculation effects are analyzed into calculate station-end turn-back capacity of First of all, this paper described and analyzed categories and operation progress of station-end turn-back, and obtained the minimal departure interval calculation formula of single track turn-back and double track turn-back, and suggested the reasonable turn- back track number when the throat area cannot operate parallel. Then, the kinetic equation, which solved the calculation method of station-end turn-back by using train traction calculation, was proposed. Finally, this paper used Beijing subway station Beijingxi under construction and DKZ4 trains as an example, and obtained the minimal departure intervals of station-end turn-back while DKZ4 train was operated under energy-saving mode and time-saving mode： the turn-back time using double tracks is much longer than that using single track. Based on these, this paper compared and analyzed the calculation results with that using average acceleration and deceleration, and shows that using train traction calculation is valuable in the capacity calculation of turn-back station.
