摘　　要：我国高速铁路经过多年发展,列车运营速度达到350 km/h,居世界前列,正在全面推进CR450科技创新工程,研究400 km/h速度等级铁路关键技术。列车速度提升后,其制动距离可能延长,进而影响高速铁路追踪间隔,降低高速铁路通过能力。为研究高速铁路运营速度提升至400 km/h后的列车追踪间隔变化规律,阐述列车运动过程与受力、车载ATP列控设备、列车运动方程式等列车追踪间隔仿真计算原理,采用模拟线路和实际线路仿真计算方法对400 km/h高速铁路列车到达追踪间隔进行研究,分析400 km/h高速铁路追踪间隔在不同动车组制动距离、不同车站咽喉长度、不同长大下坡道坡度,以及不同类型车站和股道运用方案时的差异,从而提出400 km/h高速铁路列车追踪间隔优化对策,以更好提升我国400 km/h高速铁路运营水平,推动CR450科技创新工程发展。After years of development,the speed of China’s high speed railway has reached 350 km/h,ranking among the top in the world.China is comprehensively advancing the CR450 scientific and technological innovation project and studying key railway technologies with a higher speed of 400 km/h.After the train speed is increased,the braking distance of the train may be extended,which will affect the train headway and reduce the carrying capacity of high speed railway.To study the rule of train headway after the operation speed of high speed railways is increased to 400 km/h,this paper analyzed the simulation calculation principles of train headway,such as the train motion process and force,on-board ATP train control equipment,and the train motion equation.The train headway of 400 km/h high speed railway train was studied by the simulation calculation methods of simulated and actual lines.Then the paper analyzed the train headway differences of 400 km/h high speed railway in different EMU braking distances,station throat lengths,slopes of long steep down grade,station types,and track operation schemes.Finally,it proposed optimization countermeasures of train headway on 400 km/h high speed railway to better improve the operation of 400 km/h high speed railway and advance the development of the CR450 scientific and technological innovation project.
