单线航道避让区对散货港区航道通过能力的影响

Affection of turnout anchorage on throughput capacity of fairway in coastal bulk port

随着港区规模的扩大,单线航道将极大地制约整个港区的通过能力。研究在散货港区单线航道中设置避让区,在尽可能降低航道建设投资的条件下提高航道通过能力。采用Arena仿真软件构建设置避让区的散货港区船舶航行作业系统仿真模型;研究避让区的位置及容量对航道通过能力的影响。研究结果表明,设置避让区能够显著提高航道通过能力,避让区的最优位置是航道中点处。

With the increase of port scale,the fairway greatly restricts the port’s capacity.Therefore,turnout anchorage is proposed to improve the throughput capacity and decrease the investment.This study establishes an Arena-based coastal bulk port navigation operation system simulation model;then determines the optimal site of turnout anchorage and the affection of the quantity of turnout anchorage on the throughput capacity of fairway.Finally,the results show that the throughput capacity of fairway is improved evidently by setting turnout anchorage,and the optimal site of turnout anchorage is the midpoint of the fairway.
