长江航船对江阴铁路渡轮通过能力的影响

Effect of Ships at Yangtze River on Carrying Capacity of Jiangyin Railway Ferries

应用数学理论分析了铁路渡轮穿越江面时与长江船只发生干扰的概率和平均一次干扰延长轮渡周期的时间 ,从而推导出单艘渡轮一昼夜通过能力的计算公式 .应用该公式计算了江阴铁路轮渡的日通过能力 ,并分析当长江船只日通过量发生变化时 ,轮渡通过能力的变化趋势 .

In terms of applied mathematical theory,the probability is analyzed that railway ferries are obstructed by ships when passing through the Yangtze River,so is the time to lengthen railway ferry's cycle at an average time.Thus a formula is deduced regarding the carrying capacity of a single ferry.The carrying capacity is calculated with the very formula and varying trends of ferry's carrying capacity is analyzed when the number of ships vary on the Yangtze River.These results are significant for analyzing railway transport capacity in a correct way.
