垂直型天窗占用运行图时间的分析

提出在双线自动闭塞区段计算垂直型天窗占用运行图时间的计算公式。设计通用的表格计算法,计算垂直型天窗条件下天窗外损失的时间。由计算结果可知:区段内车站增加到发线与增设中间站的效果是不同的,一般后者产生的天窗外损失时间少;同时认为即使区段内区间运行时分都小于追踪间隔时间,也产生天窗外损失时间。分析某重载线路垂直型天窗占用运行图的时间,运用表格计算法计算部分车站封闭后的天窗外损失时间。

Analysis of Occupation Time of Train Work Diagram by Vertical Window

The paper gives calculation formulas of the occupation time of the train work diagram by the vertical window on double-track auto blocking sections, designs a general table calculation method, calculates the (additional) time used by the vertical window. The calculation shows the addition of arrival/departure tracks and intermediate stations have different effects, with the latter having less additional time used under general (conditions.) It also shows that even if the on-section operation time is less than the headway, there is still additional time used. The paper analyzes the occupation time of the train work diagram by the vertical window on a heavy haul railway and uses the table calculation method to calculate the additional time used after some stations are closed.
