Abstract

Estimating the uplift capacity of offshore foundations is an important challenge in offshore engineering. According to the relative magnitude of uplift velocity to soil permeability, the soil behaviour during uplift can be categorised as drained, partially drained, or undrained. Most existing studies only consider the undrained uplift. This thesis presents a systematic numerical investigation into the uplift capacity of anchors and skirted foundations at varying velocities, ranging from drained to undrained conditions, and developed some advanced numerical techniques to incorporate potential soil-structure detachment into the modelling.
