... events, liquefaction may occur in sand layers of the foundation soil, causing a loss of strength and stability. These adverse factors that lead to the weakening of foundation soil strength need to be considered during the design phase. In the current structural design of offshore substation structures...

... models – Mohr-Coulomb and UBC3D-PLM. Soil properties were partially determined based on the experimental test results of soil samples collected in the area of interest. Soil liquefaction was evaluated using the shear stress and pore pressure criteria. Displacements, zones of plastic strains and areas...

INTRODUCTION Offshore wind energy development schemes have been launched worldwide, and thus expected to promote...

... residual seabed liquefaction in the neighborhood area of the pipeline. Simulated results exhibit that the pore water pressure and soil responses surrounding the submarine pipeline is remarkably related to the current velocity, the thickness and width of the rubber berm. Compared with unprotected case...

... ABSTRACT The liquefaction phenomenon of bulk cargo in shipping poses a significant risk to the safety of vessel navigation. However, due to the non-transparency of iron ore sand, the internal particle movement during liquefaction cannot be directly observed, leading to limited understanding...

... ABSTRACT Steel or concrete walls are installed at the toe of an embankment on loose and saturated sand for the reduction of embankment settlement caused by liquefaction. For example, the partially floating sheet-piles (PFS) method is a steel wall structure consisting of partially floating...

... consideration is the liquefaction potential of the seabed, which could reduce the capacity of the holding anchor and lead to pull-out failure. The first arrays of floating offshore wind turbines (FOWTs) have been deployed in shallow water at significant cost (e.g. Hywind Scotland, Kincardine, and WindFloat...

This study indicates that the consideration of non-homogeneous soil properties in the numerical simulation will decrease the pore pressure induced by waves; the surface soil parameters also affect the seabed response, lower surface permeability and Young's...

... ABSTRACT The recent failure of a coastal buried pipeline along the Italian coast is presented. Extensive initial investigations to assess failure causes are conducted and several shreds of evidence are identified leading to wave-induced liquefaction as the main source of failure. This thesis...

The numerical simulation consequences manifested that the maximum value of the pore pressure and soil liquefaction depth became greater in the irregular wave system, compared with the cases with regular waves. Furthermore, the random distribution of the fluid...
