Wave induced forces around buried pipelines
TLDR
In this paper, the wave induced pressure on a pipeline buried in a sandy bed at different burial depth ratios is analyzed. But the results show that wave induced pressures are significantly controlled by the wave period analyzed in terms of the scattering parameter (ka).About:

Wave-associated seabed behaviour near submarine buried pipelines
TL;DR: In this paper, a three-dimensional numerical model is developed based on the Finite Element Method to analyse the behavior of soil under the wave loading. But, it is not shown that the effect of wave obliquity on soil responses can be explained through the following two mechanisms: (i) geometry-based threedimensional influences and (ii) the formation of inversion nodes.

Influence of Wave-Induced Uplift Forces on Upheaval Buckling of Pipelines Buried in Sandy Seabeds
TL;DR: In this article, the buckling of pipelines in shallow waters subjected to surface gravity waves was investigated using Biot's consolidation model, where wave-induced uplift forces on pipelines buried in sandy seabeds were investigated.

Experimental study of soil responses around a pipeline in a sandy seabed under wave-current load
TL;DR: In this article , the effect of current on the decrease of pore pressure and its attenuation rate is more significant than that of the co-current actions, which means that the counter-current will reduce the probability of soil liquefaction.

Wave force variation due to burial of submarine pipelines in uniformly graded and low hydraulic conductivity soil
TL;DR: In this paper, the wave force variation for different buried conditions of the pipeline depends on the wave height, wave period, water depth, engineering and hydraulic properties of the seabed soil, like hydraulic conductivity, porosity, and submerged soil density.

Dynamic vertical impedance of a submarine strip foundation in ocean engineering: Water wave pressure effect
TL;DR: In this paper, the forced vertical vibration of a rigid strip foundation on a poro-elastic seabed with surface subjected to water wave pressures was studied, and three new impedance functions for foundations in ocean engineering were defined.

Wave-induced pore pressures and effective stresses in a porous bed
TL;DR: In this article, a general theory for the pore pressures and effective stresses induced in a porous bed by ocean waves is developed, where pore fluid as well as the soil skeleton are considered compressible.

Seepage force on a pipeline buried in a poroelastic seabed under wave loadings
TL;DR: The water wave induced seepage force on a pipeline buried in the seabed is investigated in this paper, where the pipeline is assumed to be rigid and not supported by any anchoring force.

Wave-Induced Pressures in Beds of Sand
TL;DR: In this paper, the applicability of traditional porous-media analytical methods to wave-induced flow in beds of sand has been verified experimentally, and the agreement between theory and experiment is found to be quite good.

Wave Induced Pressures in Permeable Seabeds
Hermann Moshagen,Alf Tørum +1 more
TL;DR: In this article, a theoretical investigation on the transmission of wave induced pressures into a permeable sea bottom has been performed, assuming that the soil water is compressible, while the grain skeleton is assumed rigid, the resulting theoretical model describes an effective mechanism by which the soil permeability affects the pressure transmission.

Wave-induced uplift force on a submarine pipeline buried in a compressible seabed
TL;DR: In this paper, a finite element simulation of the wave-induced hydrodynamic uplift force acting on a submarine pipeline buried in sandy seabed sediments subject to continuous loading of sinusoidal surface waves is presented.
