| 摘 要： | 通过建立平面二维潮流泥沙数学模型并采用实测资料对模型进行验证,模拟了钓梁二期围垦工程南堤实施前后的潮流场,分析了围垦南堤建设后对螺门码头附近海域潮流的影响及冲淤变化情况。研究结果表明:围垦南堤的实施使得码头群东侧海区流速减小较明显。围垦南堤实施后钓梁湾内海域整体呈现淤积状态,平均淤积强度在0.8 m/a左右,码头前沿海域平均淤积强度约为1.1 m/a。

| Abstract: | Based on the two-dimensional tidal current and sediment model, the field of tidal current near the sea of the secondary Diaoliang reclamation in Zhoushan was simulated due to the construction of the southern bank. After the simulation, the result was verified by the measured data. The impact on the surrounding sea and the annual change in erosion and deposition after the project were analyzed. The results show that the local current velocity in the eastern side of Luomen sea area is decreased obviously because of the reclamation project. The deposition is presented in the Diaoliang bay with the mean siltation intensity of around 0.8 m/a, as well as about 1.1 m/a of Luomen wharf apron. |
