| 摘 要： | 采用有限元三角形网格的分步杂交方法,建立了广西近岸海域的二维潮流数值模型,计算值与实测资料符合较好。采用主要分潮组合输入,模拟了研究海域的平均潮潮流场。模拟结果表明:涨急时,潮流向为东北方向,最大涨潮流速为74cm/s左右;落急时,潮流向为西南方向,最大落潮流速约100cm/s,落潮流速大于涨潮流速。近岸区域潮流为往复流,离岸边越远潮流越接近旋转流。

| Abstract: | Tidal current numerical models of the Guangxi offshore area are established using the split steps finite method with triangle grids. The average tidal current fields are simulated and the calculation accords with the observation very well. It is shown from the computed result that at flood tide, the tidal current is in the direction of north-east with the maximum speed of 74 cm/s; at ebb tide, the current is in the direction of south-west with the maximum speed of 100 cm/s. In the offing, tidal current is the rectilinear, while it is closer to the rotating farther from the seacoast. |
