Elasto-plastic Behavior of Seabed around Block by water wave Pressure

Abstract

The aim of this paper is to study numerically the seabed response around the block by the water waves. The excess pore pressure in the seabed is accumulated by the cyclic load of the waves and the block is the danger of the settlement. The method of numerical analysis is solved by the finite element method with using the Biot's two mixture theory and the elasto-plastic theory.
The gradient of the pore pressure and the shear strain generates strongly at the seabed of the block edge. The seabed around the block is stable as the permeability and the specific gravity is large.
