摘要:
［目的］ 相对于固定编组，城市轨道交通在线灵活编组涉及列车解编联挂作业，为充分考虑该作业对运行图编制的影响，需对在线灵活编组条件下的列车运行图编制关键问题进行深入研究。 ［方法］ 分析不同折返方式下列车解编联挂作业过程，提出解决列车解编联挂作业点选择、解编联挂列车数量计算方法、列车编组转换时间等运行图编制关键问题的建议。 ［结果及结论］ 解编联挂作业点宜设置在折返站，且折返站连接车辆基地更佳；列车解编联挂数量与长编组列车运行间隔、车底运行时间及解编联挂作业点位置有关；双向解编联挂比单向解编联挂的编组转换时间短，同向解编联挂作业时的作业点数量不影响编组转换时间，但有助于分担作业压力。

［Objective］ Different from fixed train formations， the on-line flexible train formation in urban rail transit involves train decoupling/coupling operations. To fully account for the impact of such operations on train diagram compilation， it is necessary to conduct in-depth research on the key issues in train diagram compilation development under on-line flexible formation conditions. ［Method］ The process of train decoupling/coupling operations under different turn-back modes is analyzed. Suggestions are proposed for key train diagram compilation issues such as the selection of decoupling/coupling operation points， the calculation method for the number of decoupled and coupled trains， and the time required for train formation conversion. ［Result Conclusion］ Decoupling/coupling operation points should be set preferably at turn-back stations， especially those connected to depots. The number of trains to be decoupled and coupled depends on the operating interval of long-formation trains， train circulation time， and the location of decoupling/coupling operation points. Bidirectional decoupling/coupling require less formation conversion time compared to unidirectional operations. While the number of operation points does not affect conversion time in same-direction decoupling/coupling operations， it helps to alleviate the operational pressure.
