摘要

摘要: 应用海洋数值模式（FVCOM）建立马迹山港三期工程海域三维潮流模型，模拟港口建设前后的潮流场，研究工程后周边海域潮流场的变化。同时结合台风“灿鸿”的风场资料，在水动力的基础上添加台风气压场和风场，建立风暴潮数值模型，分析在极端天气下三期工程的建设对周边海域流场的影响。最后结合模型计算结果，根据现场调查资料以及历史试验成果进行工程周边海域泥沙回淤以及风暴潮骤淤的计算分析。结果表明：工程后流场的变化主要集中在工程区和附近海域，变化幅度约在0.3m/s~0.4m/s之间，对工程区以外大范围海域影响较小。工程后码头水流条件得到较好的改善，水流与码头走向趋于平行。工程周边海域泥沙回淤量较小，不会对船舶航行安全造成影响，另据骤淤计算结果分析，马迹山港周边海域在台风期间的短期淤强较小，两天的淤积量不超过5cm，不具备骤淤的可能性。

Abstract: Based on a 3-D Finite Volume Coastal Ocean Model (FVCOM), tidal dynamics has been studied in the sea area around the Phase III Project of Maji Mountain Port (MMP). Furthermore, taking typhoon “Canhong” as an example, a storm surge and sediment model has also been established to study the impact of the Phase III Project on current flows and siltation during extreme weather. Tidal currents before and after the project have been compared. Model results show that the changes of tidal current mainly occur in the engineering areas with a magnitude change of 0.3-0.4 m/s during maximum flood and ebb tides. The flow condition for the port has been improved as the flow direction is changed to parallel to the wharf after the completion of the project. There is little siltation in the adjacent area, which will not affect the safety of ship navigation. Besides, the sudden siltation during typhoon period is relatively weak. The back silting in two days is less than 5 cm indicating no sudden siltation occurs.
