摘　　要：珠海桂山海上风电场是我国南海第一座大型的海上风电场,其风机基础同时具有海洋结构工程、高耸结构基础、动力设备基础和复杂软弱土地基基础四种显著工程特性,地基基础设计成为该工程的关键技术难题之一。介绍了该工程风机塔基础设计内容,重点分析了海洋土参数与桩土相互作用、风机基础结构耦合分析、频率窗口问题、基础结构疲劳分析、防腐设计、灌浆分析等基础设计关键技术。Zhuhai Guishan Offshore Wind Farm is the first big offshore wind project in the South China Sea.The wind turbine sup-porting structures have four significant engineering characteristics including offshore structure engineering, towering structure, dynam-ic equipment, both complicate and soft sea soil as well.Design of wind turbine support structures is one of the most critical and diffi-cult techinical challenges in this project.In this paper, general design contents of supporting structures are introduced.Some key tech-nical topics, like soil parameters and pile-substructure interaction, turbine-substructre-foundaton integrated analysis, frequecy window problem, structure fatigue analysis, corrosion prevention design and grouted connection design are emphasized in this paper.
