摘　　要：随着列车发车密度的提升、区间距离的增加,地铁快慢车混合开行发生越行已是不可避免的问题。本文分析地铁快慢车发生越行的基本条件,明确越行的影响因素为区间运行时分、越行站的布局和发车间隔时间等因素,总结出越行判定条件。利用成都地铁18号线实际的列车运行图,验证越行判定条件的可行性与准确性。分析越行结构单元特征,以尽可能避免越行、减少慢车待避时间为目标,实例调整快慢车的发车顺序和发车时间间隔,实现越行结构的优化。最后,对地铁快慢车混合开行,给出普适性的越行结构优化建议,对地铁快慢车行车组织优化、列车运行图铺画具有一定的参考性。With the increase of train density and interval distance,it is an inevitable problem that the crosssection of the mixed running of fast and slow trains in Metro.Based on the analysis of the basic conditions of the crossing of fast and slow trains,the influencing factors of crossing include the interval running time,the layout of crossing stations and the interval between trains,and so on.The feasibility and accuracy of the judging condition of crossing are verified by using the actual train diagram of Chengdu Metro Line 18.In order to avoid crossing and reduce the waiting time of slow train,the characteristics of the crossing structure unit are analyzed,and the departure sequence and interval of fast and slow train are adjusted by an example to optimize the crossing structure.In the end,the paper gives a universal suggestion for the optimization of the cross-over structure,which can be used as a reference for the optimization of the running organization and the drawing of the train diagram.
