防城港广钢码头超大型船舶进出港窗口期与通过能力影响研究

Study on the Impact of Super Large Vessels'Entry and Exit Window Periods and Throughput Capacity at FangChengGang Gangtie Terminal

为对防城港三牙航道与广钢101#泊位发展的匹配程度进行评估,以确定20万吨级散货船对三牙航道通过能力带来的影响,建立基于时空资源消耗理论的航道通过能力影响程度分析模型.综合考虑潮汐影响、超大型船舶与普通船舶的航行特性,以及靠离泊作业的时空资源消耗,通过构建超大型船舶进出港航行模型、潮汐模型和异质交通流模型等,对航道总体时空资源进行量化分析.研究结果表明,优化引航时间窗口策略,能够有效提高航道的通航能力,减少时空资源损失,模型计算结果与航道目前实际运行情况相符,验证了模型的有效性与准确性.

In order to evaluate the matching degree of Fangchenggang Sanya Waterway and Guangsteel 101#berth development,and determine the impact of 200000 ton bulk carriers on the passage capacity of Sanya Waterway,an analysis model of the impact degree of passage capacity based on the theory of time-space resource consumption was established.Based on the comprehensive consideration of tidal influences,navigation characteristics of very large ships and ordinary ships,as well as the consumption of space-time resources during berthing operations,the overall space-time resources of the waterway are quantitatively analyzed by constructing navigation models of very large ships entering and leaving the port,tidal models and heterogeneous traffic flow models.The results shows that optimizing the pilotage time window strategy can effectively improve the navigation capacity of the waterway and reduce the loss of temporal and spatial resources.The calculation results of the model are consistent with the actual operation of the waterway,which verifies the effectiveness and accuracy of the model.
