台湾海峡某典型深远海域风电场风机基础选型与优化

Type Selection and Optimization of Wind Turbine Foundation for a Typical Deep Sea Wind Farm in Taiwan Strait

在对深远海域某典型海上风电场风机基础选型时,综合考虑基础结构安全、建设成本、施工周期、运维难度等多方面因素,并结合场区离岸远、水深大,地质条件复杂多变、海洋环境极端恶劣的特点,分析各主流风机基础型式的特点和适用性,桩式导管架基础和多筒导管架基础因其空间桁架型结构特点适用性较强,特别是多筒导管架基础可避免嵌岩施工,优势更加明显。采用大容量单机、推进多筒导管架基础应用、推进一体化设计、优化结构体型等可有效提高台湾海峡深远海域风场风机基础建设效率,降低工程投资和施工风险。

The type selection of wind turbine foundation for a typical deep sea wind farm in Taiwan Strait is introduced.Considering the specific characteristics of the wind farm such as far distance from coast,deep water depth,complex geological conditions,and harsh marine environment,characteristics and applicability of main wind turbine foundation types are analyzed from the aspects of the safety,construction cost,construction period and operation and maintenance difficulties.It shows that the pile jacket foundation and the multi tube jacket foundation have better applicability due to their spatial truss structure characteristics.The multi tube jacket foundation can avoid rock socketed construction,which is of greater advantages.The construction efficiency,engineering investment and construction risks of the wind turbine foundation in deep sea wind farm in Taiwan Strait can be improved by adopting large capacity unit,application of the multi tube jacket foundation,integrated design and optimization of the structural shape.
