摘　　要：为了提供更为人性化的出行选择,开行快慢车模式是今后城市轨道交通发展的重要趋势。我国对不等速快慢车模式的需求已经显现,但仍然没有应用先例。因此,有必要对不等速快慢车模式系统能力计算方法进行深入研究,以期进一步完善和丰富城市轨道交通快慢车理论,提高市域快线规划和设计水平,为相关部门决策、建设、运营提供参考。结合运行图模拟铺画,提出通过采用列车模拟牵引计算的方式来确定快、慢车运行时间差,以获得不等速快慢车模式的系统能力损失;提出不等速快慢车模式的系统能力计算公式及计算步骤。本文提出的不等速快慢车模式系统能力计算方法研究,能有效指导我国城市轨道交通不等速快慢车模式的行车组织设计工作。The express/slow train organization is an important trend of the development of urban rail transit in the future to provide more humanized travel choices.In China,the demand for the express/slow train organization with unequal speed has emerged,but there is still no precedent of application.Therefore,it is necessary to conduct an in-depth study on the system capacity of the express/slow train organization with unequal speed,with a view to further perfecting and enriching the theory of the express/slow organization in urban rail transit,improving the planning and design ability of regional rapid rail transit,and providing reference for decision-making,construction and operation of relevant departments.The time difference between fast train and slow train is determined by the method of train simulation traction calculation in combination with train simulation working diagram,so as to obtain the system capacity loss of the express/slow train organization with unequal speed.At the same time,the calculation formula and procedure of the system capacity of the express/slow train organization with unequal speed are put forward.The calculation method of the express/slow train organization with unequal speed proposed in this paper can effectively guide the design of urban rail transit organization.
