京张高铁车站出站信号机设置方案优化研究

从高速铁路的发展,新型复兴号动车组投入运营等情况出发,通过对现行高速铁路设计规范对于京张高铁股道有效长650 m的车站出站信号机设置的要求,以及相关研究试验等详细的分析,提出了4个高速铁路的车站出站信号机设置方案,对各方案的适应性进行分析。结合复兴号列车在京沈高铁试验段的试验和新型复兴号动车组在京沪高铁的开行情况,对京张高铁出站信号机的设置进行了优化,京张高铁出站信号机的优化设置进一步提高高速铁路的安全性,实现到发线有效长的充分利用,进一步优化司机操纵,减少停车附加时分、提高工程经济性等,为京张高铁未来开行17辆长编组"复兴号"动车组预留了行车条件,并为今后规范的修编提供了参考依据。

Optimization Study on the Design of Departure signal of Beijing-Zhangjiakou High-speed Railway

Starting from the introduction of the development of high-speed railway and putting the new Fuxing EMU trains into operation, this article analyzes the requirements of existing code for the design of departure signal in railway stations with effective track length of 650 m on Beijing-Zhangjiakou High-speed Railway, and puts forward four design schemes of departure signal based on relevant research and analysis. The design scheme of the departure signal in Beijing-zhangjiakou High-speed Railway is optimized on the basis of the tests in Beijing-Shenyang High-speed Railway and the application of the new Fuxing EMU trains running on Beijing-Shanghai High-speed Railway. The optimization further improves the safety of high-speed railway, makes full use of the effective track length, optimizes driver's operation and improves project economy. It also reserves the driving conditions for new Fuxing EMU trains and provides references for code revision.
