摘　　要：随着客流激增,以京沪高速铁路为代表的繁忙高速铁路能力日趋紧张,需要通过优化列车运行图结构提升区间通过能力。阐述繁忙高速铁路运行图结构特点,以压缩无效时间为目的,给出运行图结构的优化原则,提出以运行线占用时间作为通过能力指标,以列车停站方案数、越行次数、区间群数、运行图四边形平均面积、运行线距离作为运行图结构指标。通过批量铺画京沪高速铁路若干客运区段列车运行图,形成运行图样本集,计算样本集中列车运行图的结构指标,分析列车运行图结构指标与运行线占用时间的相关关系。基于区间群数指标,设计运行图结构优化算法。研究表明:目前京沪高速铁路列车运行图结构存在优化空间,通过优化运行图结构,徐州东—蚌埠南区段本线高峰小时通过能力可以提高3对。With the surge of passenger flow,the capacity of busy high-speed railway,represented by Beijing-Shanghai,is becoming increasingly tense.Therefore,it is necessary to optimize the structure of train diagram to improve the section carrying capacity.Based on expounding the structural characteristics of busy high-speed railway train operation diagram,this paper puts forward the optimization principle of train diagram structure in order to reduce invalid time,and taking the number of stopping schemes,the number of overtaking lines,the number of interval groups,the average area of quadrangle of train diagram and the distance of running line as the structural index of train diagram.Then the train diagram of several sections of Beijing Shanghai high-speed railway is drawn in batches to form a sample set of train diagram,in which the structure index of train diagram is calculated,and the relationship between the structural index and the occupation time of running line is analyzed.According to the index of interval group number,the optimization algorithm of train diagram structure is designed.The research shows that there is still room for optimizing the structure of train diagram of Beijing-Shanghai high-speed railway.By optimizing the structure of train diagram,the carrying capacity of Xuzhou East to Bengbu south section in peak hours can be increased by 3 pairs.
