摘要
本文采用十五阶 Stokes 波的 Pade 逼近,获得了与实验较为一致的流场,并且利用已有的破碎波的速度、加速度场,计算了非线性波和破碎波对各种杆件作用力,比较了它们的主要特征,为海洋工程设计提供依据。
In this paper, the Pade approximation of the 15th order Stokes wave is made use of to derive flow field eseentially consistent with experiments. Then we have calculated the force and the moment exerted by nonlinear periodic and breaking waves on the piles of various kinds. Their main characteristics are compared in details. The results seem to be useful for the design of offshore structures.In this paper, the Pade approximation of the 15th order Stokes wave is made use of to derive flow field eseentially consistent with experiments.
