本文以连云港徐圩港区为例,利用二维潮流数学模型,分析总结环抱式防波堤口门航道最大横流的影响因素及相关规律,避免以往横流计算的随机性及单一性问题。研究表明:在立波特性显著的海域,环抱式防波堤口门的航道最大横流与潮差之间存在着的良好的对应关系,拟合可得最大横流的经验计算公式;结合预报潮差的累积频率分析,可求得不同累积频率的最大横流,进而指导航道设计及船舶调度管理。
Taking Xuwei Port in Lianyungang as an example, this paper analyzes and analyzes the influencing factors and related laws of the maximum cross-flow at the gate channel of embracing breakwater using the two-dimensional tidal current mathematical model to avoid the stochastic and unitary problems of cross-flow calculation in the past. The results show that there is a good correspondence between the maximum cross flow and the tidal range of the seafronts at the embankment breakwater in the sea area where the characteristics of standing waves are significant, and the empirical formulas of the maximum cross flow can be fitted. Based on the cumulative frequency of the predicted tidal range Analysis, can obtain the maximum cross-flow of different cumulative frequencies, and then guide the channel design and management of ship scheduling.
