ANALYTICAL SOLUTION FOR THE WAVE-INDUCED EXCESS PORE-PRESSURE IN A FINITE-THICKNESS SEABED LAYER

Waldemar Magda

Abstract


This paper presents the analytical solution to the wave-induced excess porepressure oscillations in permeable seabed sediments, derived for the case of limited thickness of the seabed layer. In order to show the utility of the analytical solution, a wide parameter study has been performed with a special emphasis to the relative compressibility of the two-phase (soil skeleton - porefluid) medium. The results of example computations are discussed with respect to the accuracy of the 'finite-thickness' analytical solution for the pore-pressure.
