Based on field monitoring data,the impact of scouring on large-diameter steel pipe piles in offshore wind farm is analyzed.Theoretical calculation shows that scouring of the wind turbine foundation may lead to the decrease of the o-verall stiffness of the structure,and the increase of the displacement of the foundation pile end.Field monitoring results show that the first-order frequency monitoring value of the wind turbine fluctuates around the design value within a cer-tain range.The frequency value from a longer monitoring period can basically reflect the actual on-site frequency or close to the design frequency.From the monitoring results,it can be seen that further identification and analysis are needed for the dense mode of the wind turbines.These findings provide important technical support and reference for the devel-opment and construction of offshore wind power projects.
