Abstract
Finite element models are developed using the poroelasticity formulation to analyze the instantaneous liquefaction potential of granular seabed around a benchmark rubble-mound breakwater under waves. Mathematical formulations in terms of governing equations of partially-dynamic and quasi-static cases are considered based upon the inertial terms associated with the solid phase. Liquefaction is modeled through the effective mean stress criterion. A number of parametric analyses carried out shows how much of seabed and wave parameters affect the depth and progression of instantaneous liquefaction. It is found that liquefaction may, for some instances, trigger instability of rubble-mound breakwater through the seabed under regular waves.
