| 摘 要： | 近年来我国重要的煤运通道朔黄铁路的运输能力趋于饱和，通过运输组织优化提升运能是短期内实现扩能优化的重要途径。本文在阐述朔黄铁路运量现状的基础上，运用时间序列法对2030年运量进行预测，分析4.5亿吨运量目标下的技术条件。基于朔黄铁路近期应用的一种新型自动防溜装置，围绕车站作业效率和列车运输组织两方面，通过压缩货物在站作业时间、优化天窗影响区、天窗日实行区间停车模式，对朔黄铁路运输组织现状进行优化。研究发现，当2万吨列车开行比例达到60％以上，朔黄铁路可实现年运量4.5亿吨的运量目标；通过压缩天窗影响区，全年可增开197列2万吨列车；采用区间停车模式可增加约69万吨年运量。在此基础上，提出分阶段的优化步骤，为朔黄铁路扩能增效提供技术参考。 |

| Abstract: | In recent years, the transportation capacity of Shuohuang Railway, an important coal transportation corridor in China, has become saturated. To exploit potentialities and raise efficiency, transportation organization optimization is the key way in the short term. Based on elaborating the present situation of traffic volume on the Shuozhou-Huanghua railway, the traffic volume of 2030 is predicted by the time series method, which is found that under the condition of existing equipment and transportation organization, the railroad capacity is not able to meet the transportation demand. This paper analyzes the technical conditions under the traffic volume target of 450 million tons and proposes the phased optimization steps of transportation organization on the Shuozhou-Huanghua railway from two aspects of station operation efficiency and train transportation organization based on a new type of automatic parking device. A series of optimization measures for capacity expansion and efficiency improvement are raised, such as dwell time compression of cargo at the station, skylight influence area compression and interval parking mode on skylight day. It is found that when the proportion of 20,000 tons of trains reaches more than 60%, the Shuozhou-Huanghua railway can achieve the volume target of 450 million tons. The compression of the skylight influence area could add 197 additional trains of 20,000 tons every year. And the interval parking mode could increase the annual capacity by about 690,000 tons. |
