Evaluating the hydromechanical responses of seabed–pipelines with rotated anisotropic heterogeneous seabed properties

Ocean Engineering, 2021
Abstract Seabed sediments are inherently heterogeneous and present different fabric patterns including rotated anisotropy. This work aims to investigate the effects of rotated anisotropy in seabed properties on the hydromechanical responses of seabed and pipelines.

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.

Wave-induced seabed response in shallow water

Applied Ocean Research, 2019
Abstract To simulate the wave-induced response of coupled pore fluids and a solid skeleton in shallow water, a set of solutions with different formulations (fully dynamic, partly dynamic, and quasi-static) corresponding to each soil behavior assumption is presented.

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 ...

SHORT-CRESTED WAVE-INDUCED SEABED RESPONSE VARIABLE PERMEABILITY

Journal of the Chinese Institute of Engineers, 1997
ABSTRACT The soil permeability of marine sediments varies with burial soil depth because of consolidation under overburden pressure. However, most previous investigations available for water wave-seabed interaction problem have simply assumed seabed with uniform permeability.

Wave-Induced Seabed Response in Non-homogeneous Anisotropic Seabed

2013
In a natural seabed, the soil properties is complicated, which normally vary with soil depth, change of temperature, and geographic characteristics. Furthermore, anisotropic soil behavior is commonly observed in marine sediments. However, most previous studies have been limited to the case of isotropic seabed with uniform soil characteristics.

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 ...

Modelling wave-induced 3D non-homogeneous seabed response

Applied Ocean Research, 2016
Abstract Marine seabed is often composed of non-homogeneous soil in various directions, where its response to dynamic wave loading shows much difference from the case of homogeneous soil. Most existing numerical models for wave-induced non-homogeneous seabed response have been limited to vertically layered seabed.

Response of a porous seabed around breakwater heads

Ocean Engineering, 2008
Abstract The evaluation of wave-induced pore pressures and effective stresses in a porous seabed near a breakwater head is important for coastal engineers involved in the design of marine structures. Most previous studies have been limited to two-dimensional (2D) or three-dimensional (3D) cases in front of a breakwater. In this study, we focus on the
