单线铁路旅客列车开行能力的研究

Reasonable Number of Passenger Trains Operated on Single-Track Railway

单线铁路区段 ,旅客列车的行车密度与其旅行速度之间有着密切的联系。对单线铁路旅客列车会车、越行方式和旅行速度进行了深入的分析与研究 ,找到了列车旅行速度和列车开行密度变化的一般规律。最后通过对渝怀线的计算机模拟计算 ,得出了渝怀线旅客列车开行数量的合理范围。

In single track railway sections, there is a close relationship between the traveling density of passenger trains and their traveling speeds. In this paper, an in depth analysis is made of the crossing, overtaking behaviors, and traveling speeds of passenger trains on single track railways, and a general rule reflecting the relationship between the traveling speed and the traveling density is found out. Through a computer simulation, the reasonable scope for the number of passenger trains to be operated on Xiangfan Huaihua line is obtained. This work can afford a theoretical reference for determining the reasonable number of passenger trains on other single track railways.
