重载铁路列车群组开行模式设计研究OA

The train group operation mode serves as the foundation for group operations and directly influences both the efficiency of train group operation and the transport capacity of heavy-haul railways.To improve the efficiency of train group operations,this paper investigates methods for designing train group operation modes for heavy-haul railways.First,the concept of the train group operation mode is introduced,and it is clarified that it consists of the following elements:unit train type,quantity,and formation sequence.Based on this,typical train group operation modes are classified into three categories:pure conventional train groups,pure 10 000-ton train groups,and mixed groups of conventional trains and 10 000-ton trains.Furthermore,a comparison method for train group operation modes is proposed,with three key indicators:utilization rate of passing capacity,adaptability rate of transport capacity,and adaptability rate of power supply capacity.Finally,using the Shuohuang Railway as a case study,twelve candidate train group operation modes are proposed and compared.The results show that the operation mode of"three 10 000-ton train grouping"can fully utilize the transport capacity of the Shuohuang Railway under the constraints of transport demand and power supply capacity.
