The wave-induced pore-water pressure acting on the bottom of a caisson and around the composite breakwater is analyzed by a poro-elastic theory, Biot's consolidation theory, using a finite element method. Effects of the stiffness and permeability of a rubble mound and the rocking of the caisson are examined. The spatial distribution of uplift force mainly depends on the permeability of the rubble mound. When the permeability is large, the distribution is almost linear at any phase of standing waves in front of the caisson. However, when the permeability is small, the distribution is not linear and the profile is different at each phase of standing waves; furthermore, it is affected by the magnitude of rocking of the caisson. The rocking of the caisson increases the upward pore-water pressure gradient which seems to increase the occurrence probability of a seabed liquefaction around the toe of rubble mound as one of the causes of scouring at the toe and sinking of foundation materials.
