以高速铁路的列车、动车组、动车段所为研究对象,对其进行抽象处理,并建立其数学模型。分别对列车、动车组、动车段所、运行图、接续、周转图等模型及其逻辑关系进行了阐述。合理应用软件计算结果,将使得动车段所的分布及规模设计更趋合理,可节约土地资源,节省工程投资,具有明显的经济效益和社会效益。 Taking the high-speed railway train, EMU and moving train section as the research object, it is abstractly processed and its mathematical model is established. The models of the train, EMU, moving train station, operation diagram, connection and turnaround diagram and their logical relations are respectively elaborated. Reasonable application of software calculation results will make the distribution and scale design of motor train segment more reasonable, which can save land resources and save construction investment, with obvious economic and social benefits.
