速度等级组合列车的双线铁路站间距合理性研究

A Study on the Optimal Distance between Stations of Double-track Railway Lines with Train Speeds Combination

合理确定双线铁路站间距,可以在满足运营需要通过能力的同时,适当减少中间站的设置数量,满足铁路运输需要。以图解法和分析计算法为基础,考虑列车速度组合、列车铺画顺序、列车连发对数和列车间隔时间等因素对合理站间距的影响,采用均衡铺画和集中铺画方法,分析列车运行图周期的时间构成,计算3种速度等级列车组合下的双线铁路站间距。经实例验证合理站间距计算方法的合理性,得出双线铁路区段在3种速度等级列车组合情况下的合理站间距。

The optimal station spacing of the double-track railway will allow enough passing capacity for operation and reduce the number of intermediate stations at the same time.Based on graphic method and analytical calculation method,station spacing at three different speeds for the double-track railway is analyzed considering the influencing factors such as train speed,train diagram drawing order,continuous train departure pairs,and intervals.Using equalizing drawing and concentrated drawing optimal station distancing calculation method,the time structure of the train working diagram period is analyzed,and this station distancing calculation method is vilified with case studies,and the optimal station distance for double-track lines at three different speeds is calculated.
