巽寮湾的波浪数值模拟及游艇泊稳分析

摘要

以中航巽寮湾帆艇俱乐部码头布置为依托,利用第三代风浪模型中的 SWAN 和 MIKE21 BW模型,对巽寮湾所在海域深水波要素进行了数值模拟.根据从 SWAN波浪数学模型中提取港内泊稳条件计算的起始波要素,利用 MIKE21 BW 波浪数学模型,对码头建设后各泊位前的波高分布进行了模拟.研究结果表明:NW方向波浪的影响最大.根据游艇泊稳条件,对2种防波堤方案的优劣进行了分析,2个方案都能较好地阻挡外海 S方向、SW方向和 W方向波浪侵袭港池.但是,在 NW方向的影响下,部分泊位点不能满足泊稳要求.根据计算结果和分析,方案二的防护效果优于方案一的.研究结果为巽寮湾工程的平面布置提出了技术建议.%Based on the navigation of the Xunliao Bay sailing club,the third generation wind and waves model SWAN and MIKE2 1 BW model were used to simulate the deep-water wave elements in the sea area of Xunliao Bay.According to the SWAN wave mathematical model to extract the initial wave elements in the berthing stability condi-tion,the MIKE2 1 BW wave mathematical model is used to simulate the wave height dis-tribution before the berth construction.The results show that the NW wave has the greatest influence.On the basis of the berthing stability condition of the yacht,the ad-vantages and disadvantages of the two kinds of breakwater schemes are analyzed.The two schemes can block the S,SW and W waves.However,under the influence of NW, some berths can not meet the requirements of berthing.Calculation results show that the protective effect of the scheme two is better than that of the scheme one.The re-search results can provide technical suggestions for the Xunliao Bay proj ect.
