| 摘 要： | 为研究复线布置桥梁桥区水域的通航效率,将其考虑为一个串联排队系统进行数学建模与计算机模拟。以苏通大桥与沪通大桥的桥区水域为例,计算日常与高峰两个时段桥区水域通航系统的效率。将单桥通航系统视为M/M/1型排队系统计算其通航效率,并进行两种通航系统的对比分析,找到复线布置桥梁桥区水域通航效率的两种瓶颈与瓶颈产生的机理,为复线布置桥梁的桥位选址和营运期的交通组织提出相关建议。

| Abstract: | To study navigation efficiency of the double-track bridge’s bridge area,bridge area of the doubletrack bridge is considered as a tandem queuing network to analyze their navigating efficiency.The two series of queuing system model are built to simulate bridge area of double-track bridge.Single bridge is considered as M/M/1 queuing system to calculate its navigation efficiency.The navigation efficiency on peak time and daily time has been analyzed.After analyzing the simulating and calculating results,two types of bottlenecks in the system are indentified,and the reasons of bottlenecks are found.Then,the suggestions will be given about the bridge site selection and ship traffic organization during operation. |
