单线铁路会让站到发线数量的研究

Rational Number of Arrival and Departure Tracks in Passing Stations Along Single-Track Railway

考虑到单线铁路列车实际运行中产生交会和越行方式的随机性 ,采用概率分析的方法 ,通过研究在不同开行条件下 ,产生交会、越行次数和方式的各种情况 ,建立车站到发线设置数量与交会、越行次数和方式之间的关系 ,找到直接影响车站到发线数量的主要因素 ,得出了影响其变化的一般规律。

There exists randomicity in the crossing and overtaking behaviors of trains on single track railways. The number and patterns of the crossing and overtaking of trains in various operation conditions are studied by probabilistic analysis. The relationships between the number of arrival and departure tracks and the crossing or overtaking number and patterns are obtained. The main factors that have a direct influence on the number of tracks is found out, and the variation rules of these factors versus the track number are presented. The results obtained have been used to analyze the number of tracks on Chongqing Huaihua railway.
