摘　　要：到发线有效长是铁路主要技术标准之一,货物列车到发线有效长直接影响列车牵引质量和铁路输送能力,到发线有效长过长引起工程浪费,过短则会影响线路的输送能力。以新建客货共线单线铁路为例,探讨集装箱运量占比不同时,到发线有效长对列车对数、牵引质量和通过能力的影响。The effective length of the receiving-departure track is one of the major technical parameters of a railway line.The effective length of the receiving-departure track of freight trains could directly affect the tractive tonnage and capacity.If the effective length of the receiving-departure track is too long,then it might cause unnecessary engineering cost while too short would affect the capacity.The paper takes mixed passenger and freight railway as example to demonstrate the impact on number of passenger trains,tractive tonnage and capacity that the effective length of the receiving-departure track might have when the proportion of the shipped quantity of containers is different.
