摘　　要：采用有限元软件Abaqus对海上风机固定式4桩基础侧向承载能力进行数值计算。使用三维有限元法和p-y曲线法分别对简单均匀桩的位移响应进行分析,验证p-y曲线法的准确性。使用p-y曲线法分析桩径为3.2m的4桩基础侧向承载力,并与桩径为8.0m的单桩基础侧向承载力进行对比,表明桩径为3.2m的4桩基础侧向承载力明显优于桩径为8.0m的单桩基础。所得结论为海上风机桩基础形式的选取提供参考,并为今后采用p-y曲线法对桩基础侧向承载力的快速计算提供参考。The finite element software Abaqus is used to carry out numerical calculation on the lateral bearing capacity of the fixed four-pile foundation of offshore wind turbine.Three dimensional finite element method and p-y curve method are used to analyze the displacement response of simple uniform pile,and the accuracy of the p-y curve method is verified.The p-ycurve method is used to analyze the lateral bearing capacity of the four-pile foundation with a pile diameter of 3.2 m,which is compared with that of the single-pile foundation with a diameter of 8.0 m.The result shows that the lateral bearing capacity of the four-pile foundation with a diameter of 3.2 mis obviously more excellent than that of the single-pile foundation with a pile diameter of 8.0 m.The research provides a reference for the rapid calculation of the lateral bearing capacity of pile foundations by p-ycurve method in the future.
