摘要
长大坡道下的高速铁路闭塞分区设计是一个系统工程,直接影响动车组运行安全及运输能力。为提升闭塞分区设计精度、简化闭塞分区设计工作,在总结既有规范、规定及相关研究成果的基础上,厘清平均坡度概念,优化闭塞分区算法,构建闭塞分区设计辅助系统,并结合具体项目验证系统效果。结果表明:优化算法能够更为精确地将动车组占用分区控制在6分区,且有效缩短追踪间隔40 s;闭塞分区设计辅助系统能够不受线路长度影响,将计算周期控制在1 min内。该研究成果有效提升了闭塞分区设计精度,缩短了设计周期,具有较强的工程应用性及可推广性,能够指导长大坡道下的高速铁路闭塞分区设计工作。
The signal block layout of high-speed railway with long downhill grade is a systematic engineering,which directly affects the driving safety and traffic capacity of EMU.In order to improve the design efficiency of signal block layout and simplify the work of design,this paper clarifies the concept of mean slope,optimizes the algorithm of signal block layout,designs the auxiliary system of signal block layout,and verifies the system effect with specific projects based on the analysis of existing standards and correlative researches.The research results show that:the optimization algorithm of signal block layout can accurately control the occupied block of EMU at 6,and prominently reduce the tracking interval about 40 s;the auxiliary system of signal block layout can control the calculation period within 1 min without being affected by the line length.The results of this paper have greatly improved the design accuracy and shortened the design cycle,and can direct the work of signal block layout of high-speed railway with long downhill grade on account of strong engineering applicability and popularization.
