中文摘要：
根据编组站到解系统列流到达特征,按照列流到达密度界定的1 d内货物列车到达繁忙期、空闲期和普通期3种时段,给出计算编组站到解系统通过能力的计算公式。繁忙期到解系统的通过能力为驼峰高峰解体能力与到达场用于解体货物列车技术作业的股道数之和,空闲期到解系统的通过能力为衔接到达场各方向在空闲期内图定到达的解体货物列车数之和,普通期的通过能力仍沿用现有计算公式进行计算。通过计算机模拟,给出普通期到达解体货物列车待解时间、待检时间和空费系数的经验计算公式。以济南西编组站下行到解系统通过能力计算为例,验证了所给出编组站到解系统通过能力计算方法的可行性。
英文摘要：
The paper brings forward a new formula system to describe the carrying capacity of the arriving and breaking up system in marshalling yard.A method of dividing per day into the busy,the free and the normal stages is presented according to the arrival regularities of the goods train flows in marshalling yard.The carrying capacity of the arriving and breaking up system is the sum of the different carrying capacity in the above mentioned three stages.The carrying capacity at busy stage is the sum of the humping capacity during peak time and sidings in reception yard.At free stage the carrying capacity is confined by the number of trains received.At normal stage,the traditional formula is continued to use.The experiential formula to calculate the waiting time and void coefficient in the normality is proposed by simulation.The computation results of West Jinan marshalling yard show that the method can provide more accurate and feasible ways to analyze the arriving and breaking up operations and the carrying capacity in marshalling yard.
