Planning model and calculating method of period carrying capacity on busy existed railway main-lines
-
摘要: 根据既有繁忙干线客货混运的运输组织模式和运营特征, 利用已有通过能力计算方法, 确定研究原则, 对时段性和计算区段概念进行界定, 通过列车间隔时间和不同种类列车越行等分析, 采用修正的负指数分布模型, 提出既有繁忙干线时段性通过能力的规划模型和计算方法, 并以沪宁线列车运行图某段上行区间为例进行验证。计算结果表明: 4个时段的通过能力理论值分别为53、26、49、43列, 符合每个时段繁忙干线运营实际, 模型与算法可行。Abstract: According to the actual transportation mode and operating character of passenger trains and freight trains running together on busy existed railway main-lines, the existed calculating methods of carrying capacity were analyzed, and the study principle and the definitions of period and calculated division were set down. By analyzing the time of train interval and the overtaking between different class trains, the improved mode of negative index distribution was adopted, and the planning model and calculating method of period carrying capacity on busy existed railway main-lines were advanced.An example of certain division in up train graph on Huning line was given to explain the new method.Calculation result indicates that the academic numerical values of four period carrying capacities are 53, 26, 49 and 43 respectively, which accords with the actual situation of busy main-lines, so the model and method are feasible.
