大秦铁路重载列车“速密重”合理匹配研究

A Study on the Optimal Matching of Heavy-haul Train Speed, Density and Weight of Datong-Qinhuangdao Railway

大秦铁路是国家重要的煤炭重载运输通道,为进一步提升其列车速度、密度、重量,实现"速密重"科学合理匹配,有效实现运输效率和效益最大化,在阐述大秦铁路重载运输现状的基础上,分析现有重载列车的速度、密度和重量匹配方案,研究进一步提高重载列车速度、密度、重量的途径,分别提出相应的技术措施,分析其产生的相应效果。在此基础上,提出大秦铁路提升重载列车速度、密度和重量的分阶段发展步骤,以实现大秦铁路提质增量。

Datong-Qinhuangdao Railway is an important national coal transportation corridor. It is of great significance to increase the speed, density and weight of trains, and to realize scientific and optimal combination of density, speed and weight to achieve maximum transportation efficiency and benefit. Based on elaborating the present situation of heavy-haul transportation on Datong-Qinhuangdao Railway, the paper analyzes the existing train speed, density and weight allocation scheme, studies the way to further improve the train speed, density and weight, puts forward corresponding technical measures respectively, and analyzes the corresponding effects. On this basis, the paper puts forward the phased development steps of improving train speed, density and weight in stages on Datong-Qinhuangdao railway, so as to realize the quality improvement and quality increase of Datong-Qinhuangdao railway.
