摘　　要：与普速铁路按固定闭塞方式组织列车追踪运行的控车模式不同,高速铁路由于装备了CTCS-2/3级列控系统和调度集中设备,故采取以车载信号作为行车凭证、按一次连续速度模式曲线监控高速列车运行的控车模式。基于高速铁路的这一控车特点,综合考虑列车的长度、运行速度、常用制动距离、安全防护距离、车站作业时间和闭塞分区长度等影响因素,借鉴普速铁路列车间隔时间的计算方法,给出高速铁路列车间隔时间(4种追踪间隔时间和7种车站间隔时间)的定义及其计算方法,为制定规范和统一的高速铁路列车间隔时间计算办法提供理论依据。The train control mode for normal speed railway is to organize the tracking operation between trains according to fixed block system. However, the train control mode for high speed railway is quite dif- ferent from it. Since high speed railway is equipped with CTCS-2/3 system and CTC equipment, onboard signal is regarded as the running token and high-speed train operation is monitored by continuous speed mode curve of order one. Based on the train control characteristics of high-speed railway, considering com- prehensively such influencing factors as train length, operation speed, service braking distance, safety pro- tection distance, operation time at station and the length of block section, the definitions for train headway （four kinds of train tracking intervals and seven kinds of time intervals at station） of high speed railway and the calculation methods are presented with the calculation method for normal speed railway as refer- ence. Theoretical basis has been provided for establishing specifications as well as the unified calculation method for train headway of high speed railway.
