摘要
我国自主研发的新型列车控制系统实现移动闭塞,而部分既有单线铁路线路运输能力存在不足。以移动闭塞作为单线铁路扩能手段,在论述其可行性的基础上,结合牵引计算理论,分析移动闭塞2种运行模式下区间追踪运行间隔时间、车站间隔时间的计算方法,并以青藏线格拉段为案例,分析列车运行图结构,阐述集中交会理论及该交会方式下通过能力计算方法,通过采用该方法计算格拉段应用移动闭塞的线路通过能力可提升10%,可以成为提升单线铁路能力的重要措施。
China has been developing the new train control system independently,which makes it possible to apply moving block in railway.Meanwhile,the capacity of partial single railway has been insufficient,so the paper considers moving block as the method of increasing the capacity of single railway.On the basis of describing the feasibility,the paper combines with traction calculation theory to analyze the calculating process and formula of the section tracking operation interval and station tracking operation interval in two operating mode of moving block.The paper uses Gela section of Qinghai-Tibet Railway as an example,analyzing the structure of the operating schedule of Gela section,and introducing the theory of centralizing crossing and the calculating method of passing capacity under this crossing mode.Finally,the paper uses the method to calculate the capacity of Gela section in moving block and conclude that the capacity can improve 10%comparing with automatic block,so moving block can be considered as one of the most important measures of increasing capacity.
