Abstract

Abstract

Based on the u-p form of the gener alized formulation of two-dimensional Biots 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 Biots 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 effectivest resses and pore pressure can be neglected and the governing equations can be expressed by Biots 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.
