Abstract：Considering the influence of wave pressure on the stress state of seabed soil, the pile-soil interaction system in ocean is established mathematically based on Biot consolidation theory and the fictitious pile technique. Then, such a model is solved by use of FlexPDE software, the lateral soil pressure on the pile shaft, the effective normal stress around the pile and the distribution of relative horizontal displacement and vertical displacement in the free soil field are obtained, these results can be referenced in the design and monitoring of offshore pile foundation.
