摘　　要：市域快线与地铁过轨运营条件下,对过轨区段内的通过能力进行分析计算至关重要。文章结合列车最小追踪间隔时间,将列车在区段内的实际运行过程,等效看作以平均运行速度不间断运行,构建区段等效运行线,基于此,提出过轨区段通过能力计算方法。以沈铁市域快线与沈阳地铁K2线的过轨运营为例进行分析,研究表明:过轨列车开行数量越多区段能力损失越大,在给定参数下,单一方向能力损失最高可达22列;不同制式列车的速度差越小,区段能力损失也越小,以共速运行时,区段能力仅损失4列,此时过轨列车扣除系数位于1.0~1.5之间。相关结论可为沈铁市域快线过轨运营行车组织提供参考,同时为其他城市轨道系统的过轨运营提供案例借鉴。In the situation of through operation between the urban express line and metro,the analysis and calculation of the capacity in the through sections is crucial.Based on the minimum tracking interval times,the actual operation process of the train is equivalently seen as a continuous process at the average speed,and the method of equivalent train paths is established.Based on this,the calculation method for the section carrying capacity is proposed.The case study of the urban express line of Shenyang to Tieling railway and Shenyang metro line K2 was conducted.Results show that:the more through trains operating,the greater the capacity loss in the section.Under the given parameters,the capacity loss in a single direction is up to 22 trains per an hour;the smaller the speed difference between trains,the smaller the section capacity loss we get.When all trains running at the same speed,the section carrying capacity loss may be limited within 4 trains,while the deduction coefficient for the passing train is 1~1.5 at the same time.The conclusion can provide reference for the operation organization plan of the through operation of the urban express line in Shenyang,and for similar cases in other cities.
