摘要
针对京沪高速铁路列车开行需求日益增长的现状,如何提高通过能力紧张区段的列车开行数量已成为亟待解决的问题。基于京沪高速铁路当前列车周期化开行结构,利用区段通过能力与列车停站的紧密关系,考虑区间运行时间、停站时间、车站安全间隔时间、列车和车站停站次数等约束,构建列车停站方案与运行图协同编制模型,通过列车停站方案和到发时刻的协同优化满足京沪高速铁路开行更多列车的实际需求。以京沪高速铁路下行方向列车运行图为例验证模型的可行性,优化列车的停站结构、不同速度等级列车间的待避位置和列车在途经车站的到发时刻,得到了具有更高通过能力运用水平的列车停站方案及运行图,研究结果为更好满足京沪高速铁路列车开行数量需求奠定了理论基础。
As the number of trains on the Beijing-Shanghai High Speed Railway increases, how to operate more trains in the high carrying-capacity utilization sections has become an important issue. On the basis of the existing cyclic timetable structure of the Beijing-Shanghai High Speed Railway, the close relationship between the section carrying capacity and the train stop plan was employed to build a collaborative preparation model of the train stop plan and timetable. The model considered the constraints such as the section running time, stopping time, safe interval time between stops, and the number of train stops and trains stopped at stations. With this model, the requirement of the Beijing-Shanghai High Speed Railway for more trains could be satisfied by the collaborative optimization of the train stop plan and timetable. This paper took the timetable of trains running from Beijingnan Railway Station to Shanghai Hongqiao Railway Station as an example to verify the feasibility of the model. By optimizing the train stop plan, overtaking locations of trains with different speed levels, and timetable, this study obtained a train stop plan and timetable with higher carrying capacity utilization. The research results provide a theoretical basis for better satisfying the train operation requirements of the Beijing-Shanghai High Speed Railway.
