Fatigue Response Analysis of Wind Power Pile Foundation Under Full Cycle Action of Typhoon

As an important component of offshore wind turbine foundation, steel pipe piles are subject to cyclic loads in the marine environment for a long time, especially the waves caused by typhoon, which are easy to cause fatigue damage of steel pipe piles. Based on a project example, a load pile soil ternary fatigue analysis model is proposed by combining relevant specifications, structural mechanics and finite element method, and the important factors that affect the fatigue damage of pile foundation structures in the whole cycle of typhoon are pointed out. The method of fatigue response analysis of wind power pile foundation structure in this paper has certain guiding significance for practical engineering application.
