摘要
基于二维源分布法得到不规则波浪的各个组成波作用于准椭圆沉箱的波浪力分量,应用波谱分析方法给出不同累积概率下作用于准椭圆沉箱上的不规则波波浪力。将数值计算结果与试验结果进行比较,吻合较好。应用该数值计算方法讨论了入射波向α、kD、准椭圆沉箱相对长宽比B/D与量纲一的量波浪力之间的关系,得到一些对工程应用有价值的结果。
The random wave forces of different cumulative probability on the quasi-ellipse caisson were calculated by the method of spectrum analysis. The wave force of the n-th component wave on the quasi-ellipse caisson was obtained based on two-dimensional source representation method. The numerical results were verified by comparison with the re sults of experiments. Based on the numerical method, the relation between the dimensionless wave force and the parame ters such as incident wave direction α,kD, relative length-width ratio of the quasi-ellipse caisson B/D and so on were also discussed.
