缩短自动闭塞间隔的探讨

该文讨论了两个观点:1)解决运能与运量间矛盾的主要措施之一是提高行车密度.分析表明:在双线自动闭塞区段,将列车追踪间隔由10min 减至8min 是适宜的,如果再进一步缩短列车追踪间隔,则线路通过能力的提高并不明显.2)在某双线区段,如果各类列车的制动距离差别很大时,为了提高行车密度,须采用四显示自动闭塞制度,否则,采用三显示自动闭塞制度是合理的.

An Investigation on Shortening Automatic-Block Interval

In this paper,there are two ideas are described 1.One of the most important measures of solving the contradiction between the traffic volume and the traffic capacity is to increase the density of traffic trains. Analysis shows that it is reasonable to decrease the time interval between two trains from 10 minutes to 8 minutes in the section,where the double-track automatic- block system is equipped.If the time interval is sbortened further more,the increase of traffic capacity in not evident. 2.In order to increase the density of trains,it is necessary to adopt a four- aspect automatic-block system,where the difference between the braking distances for difference types of trains is very large in the double-track section.Otherwise a three-aspect automatic-block system is reasonable.
