摘　　要：随着城市轨道交通线网架构的逐渐完善,越来越多的线路开始采用快慢车运营组织模式。针对预留开行快慢车条件的线路,如何选择越行线型式,做包容性设计,在不过多增加投资的情况下,实现开行快慢车的功能、提高未来运营灵活性,针对上述问题进行深入研究,以期为后续类似线路的设计以及相关部门的决策提供支撑和参考。在分析基本越行配线型式的基础上,提出包容性较好的单岛四线越行线外侧方案,并对越行线道岔的确定进行比选;同时,针对越行线是否兼作故障列车停车线的问题,详细对比分析各种站型增设越行线的投资增加情况,研究结果表明,单岛四线越行线外侧方案,在投资增加不多的情况下,既能满足快慢车的开行需求,又能兼顾站站停开行方案,还可兼作故障车停车线,运营灵活性及包容性较好。With gradual improvement of rail transit network architecture,more and more lines begin to adopt express and normal train operation mode.For the lines reserved for running both express and normal trains,to answer the question of how to select the overtaking line type and make inclusive design to realize the function of running express and normal trains and improve future operation flexibility without increasing investment,this paper makes an in-depth study to provide support and reference for the design of similar lines and the decision-making of relevant departments.Based on the analysis of the basic types of overtaking line arrangement,a more inclusive scheme for the outside of single-island-four-line overtaking line is proposed,and the overtaking line turnouts are compared and selected.Meanwhile,in view of whether the overtaking line is also used as the parking line for faulty trains,the additional investments for adding overtaking lines for various station types are compared and analyzed in detail.The research results show that the outer scheme of single-island-four-line overtaking line recommended in this paper can not only meet the operation needs of fast and slow trains,but also take into consideration of stopping and running scheme at stations.Furthermore,it can also be used as the parking line for faulty trains with good operation flexibility and inclusiveness.
