Research on Block Section Division of Continuous Long Heavy Grades of High-speed Railways

为解决高速铁路连续长大坡道地段CTCS-3级控车速度突降问题,研究闭塞分区划分的方法,采用牵引计算数据模型内嵌列控监控曲线模型等技术,实现高精度列车运行仿真,保证闭塞分区划分的精准与合理。基于对郑万高铁工程设计出现的问题进行分析计算,研究CTCS-2级和CTCS-3级列控系统下闭塞分区划分的具体方法和相互关系,为其他新建高铁项目提供设计参考。

In order to solve the problem of the sudden drop in the speed of a train controlled by CTCS-3 system on a continuous long heavy down grade of a high-speed railway,the methods of dividing block sections are studied.The technology of embedding the train control monitoring curve model in the traction calculation data model is adopted to realize high-precision train operation simulation and to ensure the accuracy and rationality of block section division.Based on the analysis of the problems in the design of Zhengzhou-Wanzhou High-speed Railway and the calculation of related parameters,the specifi c methods of block section division and the interrelations between such methods are studied in CTCS-2 and CTCS-3 train control systems to provide design reference for other new high-speed railway projects.
