摘要
建立了基于不规则三角形网格的考虑波浪作用的潮流泥沙数学模型,在对模型进行充分验证的基础上,对葫芦岛海域的潮流、泥沙场的进行了数值模拟,对该海区的潮流场、泥沙场特征进行了分析;对葫芦岛港柳条沟港区规划方案进行了潮流、泥沙场模拟研究。详细分析了工程前后港池和航道的流场变化,计算了航道的横流,预报了规划港区港池和航道的泥沙年淤积量,为港区的规划设计提供了科学依据。
Mathematical model with irregular triangular grids of tidal current, sediment movement are established and it also takes the wave action into account. On the basis of fully accurate verification of the model, the tidal current field and sediment field are numerically simulated for the sea area adjacent to Huludao. Also the same simulation is done for the planned Liutiaogou Harbor District of Huludao Port. Form the simulation results, current filed changed in harbor basin and navigational channel after the project has been completed is analyzed, cross current of the navigational channel is calculated, and the annual deposit volume in harbor basin and navigational channel is predicted to to lay scientific foundation for the harbor plan and design.
