摘　　要：针对青岛万达游艇码头南防波堤的堤顶越浪现象,进行了波浪整体物理模型试验研究。试验表明,ESE向和SE向波浪作用时波高较大,各泊位不满足泊稳要求,SSE向波高较小,泊稳状况满足要求。采用MIKE21BW模型,通过在原防波堤位置设置虚拟堤的方法,有效模拟了波浪的越浪现象,并对越浪后次生波在港池内的传播变形及泊稳状况进行数值计算,将计算结果与试验结果进行比较,吻合良好,表明BW模型可用于模拟堤顶越浪及其对港内泊稳状况的影响。The physical experiment is performed to study the wave overtopping over the south breakwater of Wanda marina in Qingdao. Experimental results show that the wave height in most berths are larger than the allowable values in the ESE and SE directions, while the berthing conditions of SSE are satisfactory. Based on the MIKE21 BW model, through setting a virtual dike at the location of the orig- inal breakwater, a numerical simulation model is established to simulate the wave overtopping and calculate the secondary wave propagation and berthing conditions. The results from the calculations and from the measurements in the experiment are in good agreement, which indicates that the BW model is suitable for the calculation of wave overtopping and the effects on berthing safety in harbor.
