Study for predicting the earthquake-induced liquefaction around the monopile foundation of offshore wind turbines

Earthquakes may cause liquefaction of seabed soil around the monopile foundations offshore wind turbines (OWTs), posing a great threat to safety OWTs. As an accurate prediction method has not been achieved today, further study is conducted in this paper following experimental investigation pore pressure development rule samples farm. In study, new discrimination was proposed first based on triaxial test results samples. Secondly, numerical model monopile-supported OWT developed ABAQUS. Then, various seismic waves originating from depths were applied calculate corresponding shear stress foundation. Finally, foundation different scenarios assessed using method. The research show that newly more estimating critical anti-liquefaction strength. Severe mainly occurs shallow layers OWT's structure, lateral loads top OWT, and bidirectional earthquakes will exacerbate soil.
