温州状元岙化工码头工程潮流泥沙数模研究

Mathematical modeling of tidal current and sediment on the chemical dock project of Zhuangyuan'ao Harbor of Wenzhou Port

采用水动力泥沙条件、底床冲淤演变分析及二维潮流泥沙数值模拟手段,对拟建的温州港状元岙港区化工码头工程方案进行了研究。研究结果表明:(1)工程海区潮汐属于正规半日潮类型,为强潮海区;(2)工程海区潮流性质属于不规则半日浅海潮流,潮流运动呈往复流形式;(3)工程海域深槽多年来在波浪潮流作用下一直处于稳定状态;(4)规划的化工码头走向与涨落潮流走向基本一致;(5)规划的化工码头实施后工程附近海区的涨落潮流速呈增加趋势,码头前沿会略有冲刷;(6)化工码头建设对锚地流场没有影响;(7)化工码头工程方案是合理可行的。

By sediment hydrodynamic and seabed evolution analysis and numerical modeling of two dimensional tidal current and sediment, studies are made on the planning project scheme of chemical dock of Zhuangyuan＇ ao Harbor of Wenzhou Port. The study results show： （ 1 ） Tide in the engineering sea area is nomal semidiumal tide with average tidal range over 4 m, belonging to strong tide area. （2）Tidal current in the engineering sea area belongs to shallow sea abnormal semidiumal tide current and assumes to- and- fro current. （3） The deep channel in the engineering sea area keeps stable for many years under the action of wave and tidal current. （4） The planning chemical dock direction accords basically with the flood and ebb tidal current direction. （5）The tidal current velocities at flood tide and ebb tide in the nearby sea area tend to increase after the construction of the chemical dock, and the seabed in front of the chemical dock will erode slightly. （6） The chemical dock construction has no influence on the tidal current field in the anchor ground. （7） The chemical dock project scheme is reasonable and feasible.
