Interaction between large-diameter offshore wind turbine monopiles and adjacent spudcan penetration and extraction in clay

Large-diameter monopiles are used for offshore wind turbines, while adjacent jack-up spudcan operations may induce soil deformation and compromise serviceability. Existing spudcan–pile interaction studies have focused on pile response during penetration, with limited attention to...

Helical Anchor Pullout Using a Semifluidized Bounding Surface Plasticity Model

Abstract The ultimate vertical pullout capacity of single-helix anchors in sand was explored using the coupled Eulerian–Lagrangian (CEL) technique to account for large deformation processes. A semifluidized bounding surface plasticity model was incorporated in a novel manner to i...
