波浪作用下无限深海床中无限长桩横向稳态响应分析

Transverse Steady State Response Analysis of Infinite Long Pile in Infinite Deep Seabed under Waves

考虑孔隙水的影响,在Biot固结理论的基础上,采用文克尔地基梁模型来模拟桩土之间的动力相互作用,得到了波浪作用下海床的响应,建立了波浪作用下桩的水平运动方程.分析了孔隙率、渗透系数、桩土刚度比、波浪圆频率等因素对桩的横向稳态响应的影响,为海洋开发、桩基检测等提供了依据.

With the influence of pore water concerned, a Winlder beam model was adopted to simulate the interaction of pile and soil based on Biot consolidation theory. The response of seabed under waves was obtained and the horizontal motion equation of pile built. The influences of porosity, permeability coefficient, pile-soil rigidity ratio and wave circular frequency on horizontal steady state response of pile was analyzod, which provides foundation for ocean exploitation, pile detection and so on.
