某海外厚淤泥地质海上风电PHC管桩高桩承台基础设计研究

Research on PHC pipe pile high cap foundation of offshore wind power in thick silt geology

越南风资源丰富,海上风电市场开发潜力巨大。同时,越南海上风电设计建设也具有海底地质复杂、施工船机资源稀缺、钢结构产业配套不完善等特点,这给海上风电风机基础设计带来诸多技术难题。依托越南某海上风电项目,开展了厚淤泥地质海上风电机组预应力高强混凝土(prestressed high-intensity concrete,PHC)管桩高桩承台基础型式设计研究,对特定地质下基础受力特征、设计参数进行重点分析,可供类似项目参考。

Vietnam is rich in wind resources and has great potential for the development of offshore wind power market.At the same time,the design and construction of offshore wind power in Vietnam also has the characteristics of complex seabed geology,scarce construction ship and machine resources,imperfect supporting facilities of steel structure industry and so on,which brings many technical problems to the base design of offshore wind turbine.Based on an offshore wind power project in Vietnam,this study carries out the type design research of prestressed high-intensity concrete(PHC)pipe pile high cap foundation of offshore wind turbine in thick silt geology,and focuses on the analysis of foundation stress characteristics and design parameters under specific geology.The analysis conclusion of this paper can provide reference for similar projects.
