| 摘 要： | 在经验证的3维潮流数值模型基础上,对连云港地区双导堤口门进港航道内横流特性进行研究.结果表明航道内横流垂向梯度很大,不同吃水深度的船型实际承受的横流强度存在差异,吃水较浅的船型对应的横流较强;较大横流出现在高潮位时刻附近.在设计进港航道有效宽度时,必须充分考虑横流的垂向梯度,而仅采用二维模型加以评价偏于危险.在进港船舶的调度安排上,对于抵抗横流能力弱的较小船型应避免高潮位进港,如有困难也应尽量避免高潮位时双向通航.

| Abstract: | Based on the well-verified three-dimensional tidal-current numerical model,the features of cross-flow in approach channel in Lianyungang Harbor were investigated. The results showed the vertical cross-flow distribution in the channel is significantly stratified,and the corresponding cross-flow magnitude varied to shipping vehicles with different drafts,hence a depth-averaged velocity computed by two-dimensional model is not suggested. It also showed the maximum cross-flow occurs around high tide level perio... |
