列车开行间隔对区间通过能力影响的研究

Case study on impact of time intervals between trains on section capacity

在既有旅客列车开行框架的基础上,采用不同实验方案,改变列车之间的开行间隔。运用基于列车运行图铺画优化模型的区间通过能力计算方法,计算给定实验方案的区间通过能力,进而分析出列车开行间隔对区间通过能力的影响,并从该角度出发提出改善区间通过能力的措施。

Taking Ying Tan’ Xiang Tang section as experimental background,this paper tried to find the relationship between trains time intervals and section capacity by assuming that the passenger trains were predefined.We used a method that was based on train timetable optimization model to assess section capacity.Finally,this paper proposed some measures to strengthen section capacity.
