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

Wave and current induced seabed response around a submarine pipeline in an anisotropic seabed

Ocean Engineering, 2014
A better understanding of the phenomenon of wave–seabed-structure interactions is essential for the evaluation of the liquefaction of seabed foundation under dynamic loading in the ocean environments. However, only a few investigations have been conducted for the cross-anisotropic seabed under wave pressure and marine structures, despite the fact that ...

Wave-Induced Seabed Response Around a Pipe Laid on a Poro-Elastic Seabed

Journal of Offshore Mechanics and Arctic Engineering, 1999
The stability of a pipeline has been extensively studied by coastal and marine geotechnical engineers in recent years. However, most previous investigations have been only concerned with the fluid field around the pipelines, not the wave-induced soil response below the pipelines.

PORO-FSSI-FOAM: Seabed response around a mono-pile under natural loadings

Ocean Engineering, 2019
A new 3D model is proposed within the framework of OpenFOAM for understanding the physical processes of fluid–soil interactions in the vicinity of a mono-pile that considers both waves and currents.

An analytical solution for wave-induced seabed response in a multi-layered poro-elastic seabed

Ocean Engineering, 2011
Abstract In this study, a new analytical solution for the wave-induced seabed response in a multi-layered poro-elastic seabed is developed. The seabed is treated as a multi-layered porous medium and characterized by Biot’s theory. The displacements of the solid skeleton and the pore pressure are expressed in terms of two scalar potentials and one ...

Effects of dynamic soil permeability on the wave-induced seabed response around a buried pipeline

Ocean Engineering, 2019
Soil permeability is one of key factors in the prediction of the wave-induced seabed response, which needs to be considered in the design of foundation around marine installations.

An analytical solution for the dynamic response of a seawater‐sloping seabed‐bedrock system under an oblique incident P wave

International journal for numerical and analytical methods in geomechanics (Print), 2023
Many offshore marine structures are built on seabeds with slight or considerable slopes, while most analytical studies have focused on the dynamic responses of horizontal seabeds.

Numerical analysis of wave-induced poro-elastic seabed response around a hexagonal gravity-based offshore foundation

Coastal Engineering, 2018
In order to prevent the future risk of soil and structural failures for the offshore foundations, it is essential to evaluate the seabed soil behaviors in the vicinity of the foundation under dynamic wave loadings.
