客运专线长大坡度列车追踪间隔检算分析

Calculating and Analyzing Tracking Interval of Long Slope Train on Passenger Dedicated Line

高速铁路线路的长大坡度选择是铁路设计的重要技术指标之一,因为采用的坡度情况将对工程投资、运营费用、运输能力等有较大的影响。本文通过对西成客专长大坡度运用情况的分析,研究探讨了长大坡段列车追踪间隔的检算,以及区间通过能力适应性情况。进一步肯定了西成客专长大坡度线路设计的可靠依据,也为未来高铁信号技术扩展提供了有价值的参照。

The selection of long and large slope of high-speed railway line is one of the imporiant technical indicators of railway design,because the slope adopted will have a greater impact on project investment,operating costs,transport capacity and so on.Based on the analysis of Xicheng passenger specialty’s lope operation,this paper studies and discusses the calculation of train tracking interval and the adaptability of section capacity in long and long slope section.It further affirms the reliable basis for the slope line design of Xicheng passenger specialty,and provides valuable reference for the future expansion of high-speed railway signal technology.
