大秦线2亿吨运输能力若干问题的探讨

Exploration of Problems Concerning 200 Million Tons Capacity of Daqin Railway Line

大秦线实现2亿吨、储备3亿吨的运输能力,应走大重量、低密度的道路。在最终列车重量全部实现20000t的前提下,提出过渡期的列车重量方案和相应的行车密度;检算追踪列车间隔时间和天窗占用运行图时间;分析线路在开设垂直型天窗时天窗占用运行图时间较大的原因;确定需要的通过能力;提出车站封闭的数量和保留车站的改扩建方案;提出煤炭装车站(点)、卸车地和相关线路的配套改造方案。

According to the demand of an eventual annual movement of 200 million Tons and leaving the potential capacity of 300 million tons, we shall take the solution of having heavier trainload and lower traffic density. We made an interim operation scheme to increase trainload use the corresponding traffic density, calculated the train headway and the window time, analyzed the causes of using too much time when the vertical window is executed, determined the transportation capacity, proposed the number of stations to be closed and that to be kept open, and proposed the associated upgrading solution concerning the coal loading/off-loading stations and the correlated routes.
