摘要
基于平面应变条件下的广义Biot理论 ,提出波浪直接作用下弹性海洋地基有限元分析方法。所提方法能够解决以往弹性海床解析法或各种形式的数值方法无法处理的、包含复杂边界条件的实际工况。以不透水基础下海洋地基为例 。
Based on generalized Biot's theory under plane strain condition, a finite element model is proposed to analyze the dynamic response of elastic sea floor under wave loading. Depending on the numerical model developed, practical problems with complicated boundary conditions can be simulated, which are out of the implication scopes of other analytical or numerical methods for the dynamic response of elastic seabed. As an example, numerical simulation is provided for the sea floor under impermeable foundation, and the effects of foundation on the distribution and amplitude of excess pore pressure and effective stress are studied.
