港湾对地震津波的响应
|
摘要
应用长波方程以时域方式给出任意形状和地形港湾对地震津波响应的计算方法．以等深和交深矩形港池对规则长波和地震津波的入射为例进行了计算．前者的结果与已有文献相符；后者的结果表明在由深变浅的入港口处可出现潮涌大波．
in this paper, the long wave equation and the numerical method are used to calculate the wave response induced by tsunami in a harbour with arbitrary shape and topography.The calculations apply to rectangular harbours with constant and variable depth. The response isinduced by the incidence of a regular long wave and a tsunami respectively. The results of the former are consistent with the published references and the results of the latter indicate that surgeswould occur at the harbour entrance where the depth changes from deep to shallow.
