摘　　要：直通运营模式下,城轨市域线列车与市区线列车组合运营,列车制式与开行方案的差异影响着直通区段通过能力。本文基于列车追踪与越行的4种运营模式,考虑城轨市区线对直通列车运行速度的制约,采用基于图解的计算分析方法,将列车运行周期划分为若干个列车组合,运用异质列车旅行时间差与列车追踪间隔计算列车组合时间,提出了异质列车开行方案与制式差异复合影响下的直通区段通过能力计算方法。最后,依托南京地铁2号线与S6号线的线路数据与列车运行数据,通过设计的列车停站方案验证了方法有效性,并分析了直通区段通过能力的主要影响因素。研究结果表明,直通列车与本线列车开行比例相同时直通区段通过能力最小;随着本线列车开行比例的上升、直通列车越站次数减少,直通区段通过能力不断增大;直通列车采用非站站停追踪模式或越行1次模式时,直通区段通过能力相近,且相较于越行2次模式时通过能力更大;直通列车站站停模式下,直通区段通过能力受异质列车加、减速性能影响显著。研究成果可为实施直通运营的线路通过能力可行性判定与列车开行方案的制定提供参考。The combined operation of a through-train of a regional line of an urban rail transit with a flexible operation plan and an urban line train of an urban rail transit with different standards reduces the carrying capacity of a shared-track segment under through-operation.In this study,the train oper-ation cycle was divided into several train combinations based on the four operation modes of train tracking and overtaking,considering the constraints of urban rail lines on the running speed of through-trains.Graphic-based computational analysis methods were adopted to calculate the train combination time based on heterogeneous train travel time differences and train-tracking intervals.A method for calculating the carrying capacity under the combined influence of different train plans and standard differences was developed.Finally,based on the line data and train operation data of Nanjing Metro Line 2 and Line S6,the effectiveness of the method was verified based on the de-signed train operation plan,and the factors influencing the carrying capacity of the shared-track seg-ment were analyzed.The case results show that for the same operation ratio between the through train and the train of the local line,the carrying capacity of the shared-track segment is minimal.With an increase in the operation ratio of the trains of the local line and a decrease in the number of stop-skipping operations,the carrying capacity of the shared-track segment increased constantly.When the through train adopts the non-all-stop tracking mode or overtakes the one-time mode,the carrying ability of the shared-track segment is similar to and higher than that of the two-time overtak-ing mode.In the all-stop mode,the carrying capacity of the shared-track segment is significantly in-fluenced by the acceleration and deceleration performance of heterogeneous trains.This study can provide a reference for the feasibility determination of the carrying capacity of a through-operation and the formulation of train operation plans.
