摘要:为提高长江口深水航道通过能力,减少由船舶交会宽度限制产生的延误,通过分析船舶超宽交会现状,建立仿真逻辑模型,运用Arena进行离散仿真试验。采集长江口深水航道交通流数据,设置不同的船舶交会宽度限制,对大型船舶进出港过程进行仿真,分析不同交会宽度限制对船舶通航的影响,获得被延误船舶比例、被延误船舶数量和延误时间,进而提出提升通过能力的建议。试验表明,采用Arena进行离散仿真能够量化分析超宽交会对通航效率的影响,可为航道拓宽和交通管理提供科学依据。

Abstract:To improve the capacity of Yangtze Estuary deepwater channel and reduce the delay caused by the width limit of ship encountering, the status of the super-wide ship encountering is analyzed, the simulation logic model is built, and the discrete simulation experiment is done using Arena. The ship traffic flow data are collected and the limit of ship encountering width is set to simulate the process of large ship entering and leaving ports. The influence of different encountering width limits on ship navigation is analyzed; the proportion and number of delayed ships and the delay time are obtained; the suggestions on improving the capacity are put forward. The experiment shows that the influence of super-wide ship encountering on navigation efficiency can be analyzed quantitatively by discrete simulation with Arena and it can provide scientific reference for channel broadening and traffic management.
Key words:super-wide ship encountering; discrete simulation; ship delay; Arena; Yangtze Estuary; deepwater channel

长江口12.5 m深水航道三期工程的建设,使得第五、六代大型集装箱船和20万吨级以下减载散货船乘潮航行成为可能,这极大地刺激了兼顾船型的通航需求的增长,从而引起船舶超宽交会与航道资源有限之间的矛盾加剧。航道宽度的制约使大型船舶双向交会的需求得不到满足,直接导致以下情况的发生:(1)空载船压港占用码头泊位,浪费码头资源,不利于港口生产。(2)因长江口内大型锚地资源紧张,空载船滞航占用主航道,影响航道安全,降低航道通航效率。……
