摘要：

环抱式防波堤口门航道横流一直为人们所关注。针对连云港港的连云港区和徐圩港区，利用二维潮流数学
模型分别计算不同潮型下的口门航道横流，建立潮差与横流之间的相关关系，探讨具体应用方法。研究结果表明：
连云港海域环抱式防波堤口门的航道最大横流由涨潮控制，在最大横流与涨潮潮差之间存在着良好的对应关系，拟
合曲线相关程度高。在具体应用时，可根据潮汐预报表统计涨潮潮差的累计频率，利用拟合关系求得不同累计频率
的口门航道最大横流，可为航道设计或船舶进出港管理调度提供依据。

The cross-flow in the channel at the entrance of an encircle breakwater has always been the focus of attention. For
the Lianyun and Xuwei harbor districts of Lianyungang Port，the cross-flow under different tidal ranges were simulated by a
2D current numerical modal and the correlativity between a tidal range and a cross-flow was established to explore the application. The results show that：for the encircle breakwater at Lianyungang sea area, the maximum cross-flow of channel at entrance is dominated by flood tide，and a curve with high degree of correlation can be fitted. On the application side, with the
cumulative frequency analysis of flood tidal ranges based on tide tables，the cross-flow of channel at entrance with different
cumulative frequency can be simulated by the fitting relationship，which can be used to guide design and management of inandout port ships.
