风机-基础三维一体化建模的海上风电单桩基础动力响应
Dynamic response of offshore wind turbine monopile foundation leveraging integrated three-dimensional modeling of turbine and foundation
摘要
Abstract
In response to the challenges of incomplete analytical methods for assessing the stress distri-bution in monopile foundations of offshore wind turbines under wind and wave loading,as well as the unclear mechanisms by which pile and soil parameters influence the dynamic response of the founda-tion,a three-dimensional integrated model analysis method for tower-pile-soil has been proposed.This paper is contextualized within the engineering framework of a wind power project situated in Putian,Fujian.The investigation employs the Davenport wind speed spectrum and P-M bimodal wave spectrum,wind and wave loads are simulated using the auto-regressive method and harmonic superpo-sition method separately.The investigation delves into the dynamic response of offshore wind turbine single-pile foundations under wind and wave loads.Furthermore,the research delves into the impact of pile and soil parameters on the dynamic response characteristics of the pile foundation under wind-wave loading conditions.The findings reveal that an increase in pile diameter leads to a gradual amplification of bending moments within the pile shaft,coupled with a reduction in displacement response.As the thickness of the pile foundation wall increases,the displacement and bending moment responses to wind and wave loads gradually diminish.Elevated values of soil parameters such as elastic modulus is found to mitigate the displacement and bending moment responses of the pile foundation under wind and wave loads.关键词
