Abstract

Wave-induced pore pressure and effective stresses in sea beds of finite and infinite depth are computed using the Biot theory of deformation of porous media (1962). The Biot theory is simplified to a quasi-static case and the sea bed response is determined using the Papkovich-Neuber technique of the theory of elasticity. The general theory (Biot, 1962) is compared with the quasi-static theory. -- The results are used to determine the depth of liquefaction and the depth of sliding failure, the latter being investigated via the Mohr-Coulomb failure criterion.
