摘　　要：为降低建造成本的同时获得最优的消浪效果，需要研究浮式防波堤的几何参数对消浪效果的影响，进行优化设计。采用线性势流理论用数值方法对截面为矩形的V形浮式防波堤的消浪效果进行了研究。入射波为规则波。模拟了在防波堤作用下整个流场自由面的情况，通过变换矩形截面的宽度和高度，计算了同一入射波下不同截面尺寸所对应的透射系数。计算结果表明方法可行．防波堤的截面几何参数对防波堤的消浪效果影响明显，确有根据海况进行优化选取的毖要。与长波相比，浮式防波堤对短波的消浪效果更好。In order to decrease the building cost with the best wave eliminating effect, the floating breakwater＇ s geometry parameters should be studied from the point of optimization design. Numerical method is used to study the wave eliminating effect of a V - shape floating breakwater according to the linear potential flow theory in frequency domain. Its section is rectangle and the incident wave is regular. The free surface of the fluid domain including the breakwater＇ s effect is simulated. The transmission coefficients corresponding to different section of breakwater under the same incident wave are calculated. These sections are obtained by changing their breadth and height. The results prove the method is feasible and indicate that the geometry parameters of the section play an important role in wave eliminating of floating breakwater, and there is a practical need in optimizing these parameters according to the sea state. Compared with long wave, the short wave eliminating effect is better.
