摘要
采用满足Laplace方程、线性自由表面条件、外海海底边界条件以及无穷远处散射条件的格林函数作为基本解 ,建立了可处理复杂地形港池振荡的三维边界积分方程 .利用该模型计算了变水深矩形港池的振荡问题 ,其数值解与现有模型试验结果的符合程度是令人满意的 ,从而验证了计算模型的正确性 .
A 3_D boundary integral equation method to predict the oscillations of harbors with complicated topography is presented by using the expressions of the Green's function as the basic solution, which satisfies the Laplace's equation, the linearized free surface conditions, the open_sea bottom condition as well as the radiation condition at infinity. Numerical results calculated from the present method are compared with the published experimental data for a rectangular harbor of variable depth. The comparison proves to be satisfactory and the validity of the numerical model is thus verified.
