摘　　要：针对200km/h客货共线运输组织模式,本文分别研究了在不考虑到发线数量限制、考虑到发线数量限制以及天窗布设情况下200km/h客货共线铁路通过能力分时段计算方法。研究表明,不考虑到发线数量限制条件,低等级列车可以采用有越行、多列追踪的方式通过区段,线路通过能力较大;考虑到发线数量限制条件,低等级列车可以采取有越行追踪的方式通过区段,追踪列车的数量与车站到发线数量有关,到发线数量对线路通过能力有较大影响;考虑天窗布设情况下,由于全线综合维修天窗不连续,全程列车不仅受本段综合维修天窗的影响,而且受相邻区段的天窗影响。As for 200 km/h mixed passenger and freight railway,the calculation method of carrying capacity in different time of a day is studied under different conditions including no limit of the number of arrivaldeparture lines,and the limit of the number of arrival-departure lines and the arrangement of maintenance time.The research shows that,without considering the limit of of arrival-departure lines,low-level trains can adopt multiline and multi-train tracking to pass through the section,which would increase the line carrying capacity.Considering the limit of arrival-departure lines,low-level trains can adopt multiline tracking to pass through the section.In this case,the number of tracking trains is related to arrival-departure lines in the station,and the arrival-departure lines have great influence on the carrying capacity.What’s more,as the maintenance time are not continuous,the whole train is affected by the maintenance times of this section and adjacent sections.
