摘　　要：利用高速铁路动车组牵引计算系统,以京沪高速铁路下行方向为实例,研究动车组制动距离对列车追踪间隔时分和车站进路占用时分的影响。在最高时速350 km条件下,采用CTCS3-300H型列控车载设备,对比CR400BF型动车组,CR400AF型动车组的制动距离更短。中间站通过追踪间隔时分、枢纽车站到达追踪间隔时分、枢纽车站接车进路占用时分均减少。依据上述参数的变化情况,特定条件下,客运区段的区间通过能力可提升6.45%~12.5%,枢纽车站的接车端咽喉通过能力可提升3.89%~9.91%。在保证行车安全的前提下,缩短制动距离是提升高速铁路通过能力的有效措施。Taking the down direction of Beijing-Shanghai high-speed railway as an example,the influence of EMU braking distance on train tracking interval time and station route occupation time is studied by using EMU traction calculation system of high-speed railway.Under the maximum speed of 350 km/h,the braking distance of CR400AF EMU is shorter than that of CR400BF EMU by using CTCS3-300H train control on-board equipment.The tracking interval time of the intermediate station,the arrival tracking interval time of the hub station,and the time occupied by the receiving route of the hub station are reduced.According to the changes of the above parameters,under specific conditions,the section carrying capacity of passenger section can be increased by 6.45%~12.5%,and the terminal throat carrying capacity of the hub station can be increased by 3.89%~9.91%.On the premise of ensuring traffic safety,shortening braking distance is an effective measure to improve the carrying capacity of high-speed railway.
