摘要
在分析列车运行图结构的基础上,深入研究了繁忙干线V型天窗的特点,建立了V型天窗对线路通过能力的影响的数学模型,以分析V型天窗中影响线路通过能力的关键因素.对各影响因素的灵敏度分析表明,线路通过能力的扣除与天窗时间和天窗分段长度成正比,与货物列车速度、列车间隔时间成反比.
Based on the analysis of the structures of train diagrams, the features of V form skylights on busy trunk lines are studied, and a mathematical model is proposed to analyze the key factors in a V form skylight, which influence the carrying capacity of railways. Sensitivity analysis on the factors in a V form skylight shows that the deduction of carrying capacity of a railway line is directly proportional to the time spans and the lengths of V form skylights and inversely proportional to the speed of freight trains and the intervals between trains.
