海龙湾波浪场整体数学模型研究

为了深入研究海龙湾港区的波浪情况,建立了海龙湾波浪场整体数学模型,对港区内外波浪场进行分析研究。利用扩展抛物型缓坡方程完成由外海到港区口门的波浪推演,模拟波浪由外海向近岸港区的传播过程。再利用椭圆型缓坡方程,模拟港区内的波浪分布情况。研究结果表明:推荐设计方案的港区防波堤对主波向的波浪做到很好的掩护,相较比选方案来说港内波浪条件更好,等值线图表明设计推荐方案是合理可行的。总体说来,该模型对海龙湾波浪场的数值模拟是有效的,为工程实际提供了科学合理的参考。

Whole mathematical model of wave field at Hailong bay

To further study the wave field at Hailong bay,we establish the whole mathematical model to analyze the wave field inside and outside the port.Using the extended parabolic mild-slope equation,we finish the sea-to-port entrance wave deduction and simulate the wave transmission from the offshore to the near-shore.By the elliptic mild-slope equation,we simulate the wave distribution within the port area.The result shows that the recommended breakwater can well shelter the main wave and the recommended scheme is reasonable and feasible.Compared with scheme comparison,wave conditions of recommended design scheme is much better.And the contour map indicates that recommended design scheme is feasible.Overall,the whole mathematical model of wave field at Hailong bay is effective,and it can provide a scientific reference for the engineering practice.
