摘　　要：我国高速铁路成网运营后,速度等级与停站结构差异的多方向列车在部分区段交汇运行,区间通过能力不能按平行图模式利用,区间通过能力存在一定程度的损失。研究分析了高速铁路通过能力利用构成,给出高速铁路通过能力损失的定义及影响因素,提出能力损失分为计划型和实际型2类;针对计划型能力损失,根据列车占用区间时空顺序及最小间隔时间,提出压缩后的列车运行图可以划分为占用、妨碍、损失3类状态区域,结合各类状态区域时空面积建立了一套基于运行图分区的高速铁路通过能力损失判别与定量计算方法;以某高速铁路为例进行了验证,计算结果表明给定列车开行结构条件下案例线路的通过能力损失率为0.287,提出的高速铁路通过能力损失计算方法有效。As the operation network of China’s high speed railways forms,multi-directional trains with different speeds and station stopping structures run together in some sections,and the carrying capacity within the section fails to be used according to the parallel train diagram,and the carrying capacity within the section has a certain degree of loss.This paper analyzed the utilization states of carrying capacity of high speed railways and provided the definition and influencing factors of carrying capacity loss of high speed railways.The capacity loss was classified into planned capacity loss and actual capacity loss.For planned capacity loss,the compressed train working diagram was divided into three types of status regions based on the sequence of trains on the railway section and the minimum interval time,which were the occupancy region,obstruction region,and loss region.According to the spatiotemporal area of various status regions,an identification and quantitative calculation method for carrying capacity loss of high speed railways based on train working diagram partitioning was established.By taking a high speed railway as an example,the calculation results show that the carrying capacity loss rate of the case line is 0.287 according to the given train operation structure,and the proposed calculation method for carrying capacity loss of high speed railways is effective.
