摘　　要：采用基于Boussinesq方程的平面二维波浪数学模型,将潜堤作为动边界处理,对潜堤掩护港域的波浪传播变形进行数值模拟研究。首先,采用Ohyama等的潜堤试验数据,就数学模型对人工潜堤上波浪传播变形问题的适用性进行验证探讨;其次,针对某渔港外部潜堤防护工程,采用数学模型进行波浪场推算,分析潜堤的消浪过程,同时将模拟得出的波浪透射系数与国内外经验公式计算值进行对比,结果表明该数值模拟方法是有效的。A horizontal 2D numerical model of wave based on the Boussinesq equation is used to study the simulation of wave transformation in the harbor area protected by submerged breakwaters, which the submerged breakwaters are handled as the moving boundaries. The numerical model is first tested to prove its applicability in the simulation of wave transformation over submerged breakwater by the experimental data proposed by Ohyama, et al. Then, the numerical model is used in the water area outside a fishing port which is protected by a submerged breakwater. The processes of wave dissipation are analyzed, and the wave transmission coefficients obtained by simulation are compared with the calculated values of the empirical formulas at home and abroad. The results show that the present simulation method can effectively simulate the wave transformation over the submerged breakwater.
