A consolidation finite element method is presented to solve the transient response of seabed, and an improved circular slip method is developed to analyze the stability of coastal structures. Dynamic elastic consolidation theory and linear permeability theory are employed to get a solution for the responses of pore pressure, displacements and effective stresses in a saturated seabed with arbitrary boundary conditions under the action of regular and irregular waves. The influence of wave induced excess stresses on the slip surface is considered in the stability analysis. The spatial and temporal variations of pore pressure compare well with experiments. Calculations show that if the influence of wave induced seabed response is considered, the stability coefficient of coastal structures will decrease, and it is related to wave amplitude and the permeability of seabed soil.

应用动弹性固结有限元法,求解了随机波浪作用下饱和海床土体中的孔隙水压力、有效应力和位移的瞬态响应,并对海洋建筑物的稳定性进行分析。建立的有限元计算模型中采用了动弹性固结理论和线性渗流理论,海床可为具有任意边界条件的分层分块弹性多孔介质;利用简单条分法对海床和建筑物进行稳定性分析,在滑动面上考虑波浪附加应力的影响。孔隙水压力响应的理论计算结果与模型实验的量测值吻合的较好。计算表明,近海工程中考虑海床土体受到的波浪附加应力时,海床和建筑物的整体稳定安全系数将降低,降低幅度主要与海床面上的波浪压力、海床的渗透性有关。

Based on the u-p form of the generalized formulation of twodimensional Biot's theory of dynamic consolidation, the finite element numerical procedure in time domain is developed to evaluate dynamic response of saturated seabed. The governing equations which are composed of static equilibrium conditions and Biot's consolidation equation can be regarded as a special case. In comparative examples, the results from the degenerated method proposed agree well with the analytical solutions. In general, the effect of soil skeleton acceleration on effective stresses and pore pressure can be neglected and the governing equations can be expressed by Biot's theory. The upper coarse sand layer of layered seabed will not reduce the amplitudes of pore pressure remarkably at the shallow zone near the seabed surface, therefore the possible maximum liquefaction depth will not change.

由Biot二维广义动力固结理论的形式基本控制方程出发,忽略孔隙流体的加速度,提出了饱和海床动力反应的时域有限元数值解法.联立静力平衡条件和Biot固结方程的退化法所得到的数值解可视为其特例.在比较算例中,退化法得到的超静孔压和有效应力幅值沿海床深度的分布与解析解一致.一般情况下,土骨架的加速度对海床的有效应力和超静孔压影响很小,控制方程可以退化为Biot理论.成层海床上部的粗砂层不会使超静孔压幅值在海床表面下较浅的深度内迅速衰减,难以改变海床的瞬时循环液化深度.

On analysis of the distribution of seabed stresses and soil skeleton displacements due to water waves, the effects of parameters of waves, elastic module, degree of saturation and seabed thickness on the distribution have been considered. Then the horizontal displacement, the vertical displacement of the soil skeletal frame have been calculated for saturated and non-saturated seabed. These results are worth for the design of ocean structure.

系统分析了波浪作用下海底底床中的应力及位移分布 ,考虑了不同加载波参数、弹性模量、饱和度及底床厚度对底床应力分布的影响 ,并计算了不同砂质的土骨架水平位移和垂向位移 ,比较了饱和底床和非饱和底床 ,这些结果可应用于海洋结构物的设计 .
