摘    要:采用大凌河实测长系列河道径流及水下地形等数据, 通过建立水动力数值模型, 综合考虑潮流和河道径流的影响, 对大凌河口的潮流进行模拟, 探讨大凌河口及辽东湾北部海域水动力过程的主要特征. 结果表明: 大凌河口附近海域的海流以潮流为主, 具有明显的往复性质. 潮流总的运动趋势是, 涨潮主流向为北东, 落潮主流向为南西. 大潮流速大于小潮流速, 涨潮流历时与落潮流历时几乎相当. 最大涨潮流速约为0.52 m/s, 最大落潮流速约为0.4 m/s, 潮流涨落平均潮流强度的分布大体和该海域等深线相适应.

关 键 词:水动力   数值模拟   潮流   大凌河   辽东湾

Abstract:Based on the long series of measured data about Dalinghe River runoff and underwater terrain, the hydrodynamic numerical model is established to simulate the tidal current of Dalinghe River estuary and the main characteristics of hydrodynamic process in the estuary and northern sea area of Liaodong Bay are discussed considering the influence of tidal current and river runoff. The results show that the ocean current in waters around the estuary is mainly tidal current with obvious reciprocating nature. The general movement trend of tidal current is northeastward at high tide and southwestward at low tide. The speed of spring tide is larger than that of neap tide and the duration of flood current is almost equal to that of ebb current, with the maximum flood speed of 0.52 m/s and maximum ebb speed of 0.4 m/s. The distribution of average tidal current intensity during flood and ebb is roughly consistent with the sea depth contour.
Keywords:hydrodynamic force  numerical simulation  tidal current  Dalinghe River  Liaodong Bay
