Random Wave-Induced Seabed Response

2013
In this chapter, unlike most previous investigations for wave-induced soil response, a simple semi-analytical model for the random wave-induced soil response is established for an unsaturated seabed of finite thickness. Two different wave spectra, the B–M and JONSWAP spectra, are considered.

Dynamic response of porous seabed to ocean waves

Computers and Geotechnics, 2001
In this paper, dynamic response of a seabed to ocean waves is treated analytically on the basis of a poro-elastic theory. The seabed is modelled as an isotropic homogeneous material of finite thickness. Most previous investigations for the wave-seabed interaction problem have treated the problem in the well-known quasi-static state.

A semi‐analytical method for the wave‐induced seabed response

International Journal for Numerical and Analytical Methods in Geomechanics, 1994
AbstractA general semi‐analytical method is presented for the analysis of seabed response under wave action during a storm. The seabed is idealized as a poro‐elastic medium filled with a single compressible fluid with anisotropic flow. The coupled process of fluid flow and deformation of soil skeleton is formulated in the framework of Biot's theory.The

Numerical analysis on random wave-induced porous seabed response

Marine Georesources & Geotechnology, 2017
ABSTRACTResearch on the response of random wave on offshore structures has received great deal of attention of many researchers and engineers in the design of marine structures. Most previous investigations have been limited to the regular waves. In this paper, based on Longuet–Higgins random wave theory and finite element method, a numerical model for

Updated Free Span Response Near the Seabed

Volume 2: Subsea Technology; Ocean Space Utilization
Abstract Most offshore pipelines, umbilical’s, and cables installed exposed on the seabed may exhibit free spans. These slender circular cylinder structures, when subjected to external flow, may experience vortex-induced vibrations (VIV), potentially leading to significant fatigue damage.

Response of Cross‐Anisotropic Seabed to Ocean Waves

Journal of Geotechnical Engineering, 1992
Quasi‐static field equations for fully saturated porous elastic media, based on Biot's theory (1972‐1973), established in the writer's previous works (1989‐1990) are used in order to describe the behavior of such materials under wave ocean loading. A brief description of cross anisotropy with a vertical axis of symmetry (orthotropy) is given.

Cnoidal wave induced seabed response around a buried pipeline

Ocean Engineering, 2015
The evaluation of wave-induced pore pressures and effective stresses in a poroelastic seabed is important for coastal and ocean engineers in the design of marine structures. Most previous theoretical investigations have focused commonly on the Stokes wave induced seabed response. In this paper, a cnoidal wave–seabed–pipeline system is modeled using the
