直立码头前沿波高模型及数值模拟

Wave height model and numerical simulation of frontier of vertical wharf

立足港区平面规划布置实际需求,对防波堤掩护下的港域进行波浪物理模型试验。并基于MIKE21-BW模型的数值模拟,研究不规则波以一定角度入射直立式码头后泊位的波高情况。数值模拟及物理模型试验均可考虑波浪由外海传向近岸的绕射、反射及折射等过程。通过上述两种手段对比码头前沿提取的波高数据,结果吻合良好,说明MIKE21-BW模型能够应用于近岸波浪的传播变形及港区波浪条件研究中,为港区的平面布置提供科学的研究依据。

Based on the actual requirements of plane layout of port area,the port area under the cover of the breakwater is subjected to wave physical model tests.And based on the numerical simulation of the MIKE21-BW model,the wave heights of irregular waves incident on the berth behind a vertical wharf at a certain angle are studied.Both numerical simulation and physical model experiment can take into account wave's the diffraction,reflection and refraction from sea to shore.Comparing the wave height data extracted by the terminal front through the above two methods,the results are in good agreement,indicating that the MIKE21-BW can be applied to the study of nearshore wave propagation and wave condition in the port area providing a scientific research basis for the layout of the port area.
