摘　　要：结合国电乐亭月坨岛海上3号测风塔的方案设计,对三边形测风塔桩基础的设计荷载及组合、有限元内力分析及桩基承台抗弯计算等内容进行了论述。经与四边形桩基础布置方案比较,三角形测风塔桩基础方案具有明显的经济优势。Based on the design plan of the National Electric＇s Yuetuo Island No. 3 offshore anemometer tower in Yueting County, this paper presents a case study of the design and analysis of the foundation of an offshore triangular anemometer tower. The load magnitude and combination aspects of this structure are discussed. The finite element analysis of the foundation components and the estimation of the bending moments in the pile-cap are also introduced. Compared with the quadrilateral pile foundation distribution, the triangular pile-cap option has the advantage in the construction cost.
