为了研究削角直立式防波堤上波浪力的分布规律,寻求适合于削角直立堤的波浪力计算公式,通过对削角沉箱防波堤的不规则波物理模型试验,得到了作用在防波堤上的水平波浪力、削角斜面上的竖向力以及堤底面上的浮托力系列,经与合田良实直立堤波浪力计算公式对比,表明作用在防波堤迎浪面的波压力分布与合田方法相近。根据分析检验,提出了相应的水平波浪力、斜面竖向波浪力以及堤底浮托力的不确定系数,并建议对斜面竖向波浪力的计算值进行适当调整。

In order to study the distribution of wave forces acting on chamfered vertical breakwaters and to find out a formula to calculate the wave forces,irregular wave experiments on physical models of chamfered vertical breakwaters were carried out. The series of horizontal forces, vertical downward forces on the slope and the uplift forces on the breakwaters were obtained. The wave force distribution on the breakwaters is similar to that of Goda method. Based on the analysis, the uncertainty coefficients for horizontal forces, vertical downward forces and uplift forces are presented. A modification for the calculation value of the vertical downward force is proposed.
