松软地层某风电场风力发电机组基础设计

The Foundation Design of a Wind Farm in Soft Ground

风力发电是最有竞争力的替代能源,已经成为全球能源领域的最佳投资方向之一。风力发电朝着高塔筒、大容量、长叶片的方向发展,对风力发电机组基础的设计提出更高的要求。本文结合工程实例,探讨了松软地层中PHC预应力管桩承台基础的选择、布置与计算,并通过桩基试验与检测,验证了PHC预应力管桩承台基础的可行性,以期为以后同类工程的设计提供可借鉴的经验。

Wind power is the most competitive alternative energy and has become one of the best investment directions in the global energy field.Wind power generation is developing towards the direction of high tower,large capacity and long blades,which puts forward higher requirements for the design of wind turbine foundation.Combined with engineering examples,this paper discusses the selection,layout and calculation of PHC prestressed pipe pile cap foundation in soft ground,and verif ies the feasibility of PHC prestressed pipe pile cap foundation through pile foundation test and detection,which was expected to provide reference experience for the design of similar projects in the future.
