本文采用边界元与有限差分相结合的数学模型研究了半圆型防波堤上波浪压力的作用规律 ,并总结出了适用于堤顶淹没、半淹没和不淹没情况下的总压力和抗滑稳定系数的简化计算公式。简化公式计算结果与物理模型试验结果符合良好。

The wave forces acting on the semi circular breakwaters are studied by a hybrid numerical method of Boundary Element Method and Finite Difference Method in this paper.A simple formula for calculating the wave forces on the breakwater is summarized,which can be applied in the cases when the crests of the breakwater are submerged,exposed as well as submerged and exposed alternatively.The comparisons are made between the results of simple formula and the experimental data,and good agreement is obtained.
