摘要: 为了高效计算铁路车站咽喉的通过能力, 提出以进路为对象、以咽喉运用饱和状态下进路占用时间推算为核心的5步计算法。推导了基于概率论多除少补原理的一元多次多项式方程以标定关键参数, 并设计了以平行进路关联图为基础的完全子图搜索算法以确定方程系数, 以东莞站广州方向咽喉为例进行了计算。计算结果表明: 咽喉通过能力为503列, 占用43#、45#、53#道岔的列车数为102列, 计算时的通过能力利用率达到75%。可见, 该计算方法具有较强的可操作性。Abstract: In order to calculate the carrying capacity of railway station bottleneck efficiently, a new kind of calculating method with 5 steps was put forward. The method took station bottlenecks' routes as object and the projection of routes' holding time under saturation condition as core. A polynomial equation of higher degree with an unknown variable was deduced by applying probability theory, and the equation could calibrate the key parameters in the calculating method. Algorithms for searching complete sub-graphs based on parallel-route relation graph were devised in order to determine the equation coefficients. Guangzhou orientation bottleneck in Dongguan Station was as a calculation example. Calculation result shows that the carrying capacity of the station bottleneck is 503 trains, 43#, 45# and 53# turnouts are taken up by 102 trains, and the carrying capacity utilization ratio is 75%. So the calculating method has good maneuverability.
