摘　　要：建立三维潮流数学模型,采用潮位以及分层流速流向实测资料对模型进行验证,对天津港大沽口港区东、北防波堤延伸方案的潮流分布进行模拟研究。结果表明,港区附近表层与0.6h水深处流速大小较为接近,底层流速明显较小,各层的流向较为一致;港区现状口门布置条件下,口门附近流速和横流相对较大;口门东、北防波堤延伸工程实施后,口门航道附近水流流态明显改善,横流流速也进一步减小;从水流条件考虑,该延伸方案是合适的。We establish a three-dimensional tidal current mathematical model,verify the model by the measured tidal level and stratified velocity and flow direction data,carry out simulation study on the tidal current distribution of the east and north breakwater extension scheme of Dagukou Port area of Tianjin Port. The results show that the velocity distribution of the surface layer near the port area is basically the same as that of the 0. 6 h water depth,the velocity of the bottom layer is obviously smaller,and the velocity direction of each layer is relatively consistent. Under the condition of port entrance current layout,the velocity and cross flow near the gate are relatively large. After the implementation of the extension project of the breakwater in the east and north of the entrance,the flow pattern near the entrance channel is obviously improved,and the cross flow velocity is also obviously reduced. Considering the improvement of flow conditions,the extension scheme is suitable.
