... wave-induced residual pore pressure liquefaction Proceedings of the ASME 2023 42nd International Conference on Ocean, Offshore and Arctic Engineering OMAE2023 June 11-16, 2023, Melbourne, Australia OMAE2023-101571 FRICTION WEAKENING MECHANISM OF SANDY SEABED AROUND A SUCTION PILE UNDER OCEAN WAVE...

... is a function of pore-fluid pressures in the seabed. The proposed model is verified against the existing experimental data. The numerical examples show that dynamic permeability has a significant effect on wave-induced dynamic soil responses, which will cause a deeper and wider liquefaction zone compared...

... Abstract This study focused on the potential liquefaction due to earthquake shaking of a gravity based structure (GBS) located off the northeast coast of Italy in the Adriatic Sea. The reinforced concrete GBS is 88 m wide by 180 m long and is underlain by a sand unit with variable thickness...

... Abstract This paper presents the results of an experimental study of seabed liquefaction under progressive waves. Firstly, during preliminary tests, the physical and mechanical parameters of the soil selected as the subgrade material were determined. A series of monotonic triaxial shear tests...

... waves) in tsunami earthquakes are amplified by secondly submarine landslides, induced by the liquefaction of the sea floor due to the strong vibrations of the earthquakes. As pointed by Kanamori (2004), tsunami earthquakes are significantly stronger in longer waves than 100 s and low in radiation...

... for a progressive densification under cyclic loading, which is responsible for the soil liquefaction phenomena in undrained conditions. Finally, some implications of these issues for the practical design of offshore monopiles will be discussed and some specific recommendations for the design procedures...

... 09 01 2009 Soil liquefaction and associated ground failures have caused much damage to coastal and waterfront structures in the past major earthquakes. The prevalence of liquefaction in the coastal environment necessitates the development of appropriate remediation countermeasures...
