To　address　the　issue　of　the　influence　of　pile-soil　interaction　on　the　seismic　response　of　super-large　monopile　offshore　wind　turbine　structures,　based　on　the　IEA　15　MW　prototype　of　a　fixed　monopile　offshore　wind　turbine,　Abaqus　was　used　to　develop　two　structural　models　of　the　wind　turbine　considering　pile-soil　interaction　and　mud　surface　fixation,　and　the　pile-soil　interaction　was　simulated　by　a　set　of　nonlinear　springs.　Considering　the　combined　effect　of　wind-wave　and　earthquake,　the　influence　of　pile-soil　interaction　on　the　dynamic　response　of　super-large　fixed　monopile　offshore　wind　turbine　structure　was　analyzed.　Results　indicate　that　for　super-large　offshore　wind　turbines,　the　pile-soil　interaction　effect　reduces　the　eigenfrequency　of　the　wind　turbine　support　structure　by　3%　-　6%,　and　the　dynamic　response　of　large　megawatt　wind　turbines,　when　considering　the　pile-soil　interaction,　is　significantly　greater　than　that　of　the　mud　surface　fixed　wind　turbine　model,　and　the　larger　the　size　of　the　offshore　wind　turbine,　the　more　significant　the　pile-soil　interaction　effect　is.　©　2024　Beijing　University　of　Technology.　All　rights　reserved.
