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 appli- cation. The results show that ： for the encircle breakwater at Lianyungang sea area, the maximum cross-flow of channel at en- trance 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 in- and-out port ships.
