Abstract: Based on the research of bearing capacity of offshore wind turbine in China, this paper established the calculation
model of large-diameter offshore wind turbine foundation and seabed through theoretical analysis and numerical simulation by
using the large-scale general finite element software COMSOL. Through this model, the lateral bearing capacity of large-diameter
offshore wind turbine pile foundation under lateral loading was calculated, the influence of lateral loading, pile diameter and other
parameters on lateral displacement and pile bending moment of offshore wind turbine pile foundation was analyzed, and the results
can be used for similar projects.

Key words: large-diameter pile; offshore wind turbine foundation; lateral displacement; bending moment; numerical simulation
