摘　　要：为满足城市轨道交通线路夜间行车需求,提出了全线单线双向行车模式,即全线2条正线中一线双向行车一线维修;研究了全线单线双向行车模式下列车在站交会方式及区间运行线铺画方式的特点,提出了在各运行线铺画方式下各区间的运行图周期通式;构建了确定线路最小区间运行图周期的0-1非线性规划模型,并改写为0-1线性规划模型以方便求解;研究了城市轨道交通站站停线路的夜间行车能力计算问题;选择一条在建城市轨道交通线路,应用0-1线性规划模型计算了全线单线双向行车模式下,线路在前一天23:00至第二天05:00时间段共6 h的夜间行车能力,对比分析了不同配线条件下线路夜间行车能力。结果表明:全线单线双向行车模式下线路夜间6 h总行车能力为10对,在站增设配线可实现夜间行车能力提升;所提出的0-1线性规划模型计算简洁、结果可靠,可用于不同配线条件线路夜间行车能力计算。A full line single-track bidirectional operation mode,in which one of the two main tracks was used for train operation from both directions and the other one was under maintenance,was proposed to meet the nighttime driving needs of urban rail transit lines.The characteristics of train intersection mode at stations and section operation line drawing mode under the full line single-track bidirectional operation mode were studied,and a general formula for train working graph cycle in each section under the drawing mode of each train operating line was proposed.A 0-1 nonlinear programming model to determine the minimum section train working graph cycle of the line was constructed,and rewritten as a 0-1 linear programming model for ease of solving.The problem of calculating the nighttime driving capacity of urban rail transit which serves all stations was studied.An urban rail transit line under construction was selected,and the 0-1 linear programming model was applied to calculate the line s 6-hour nighttime driving capacity in the period from 23:00 of the previous day to 05:00 of the next day under the full line single-track bidirectional operation mode,and a comparative analysis was conducted of the nighttime driving capacity of the line under different layouts of siding tracks.The results show that the line s total 6-hour nighttime driving capacity under the full line single-track bidirectional operation mode is 10 pairs,and the nighttime driving capacity can be increased by adding additional siding tracks at the station.The proposed 0-1 linear programming mode is simple in calculation and reliable in results,which can be used to calculate the nighttime driving capacity of lines with different layouts of siding tracks.
