Finite Element Analysis and Optimization Design of Pile Foundation for a Wind Field Pile

由于风力发电风机高耸结构对建筑设计要求的特殊性,风力电机塔架高,基础面积小,加之受风力影响,风电工程荷载的特殊性。当天然地基不能提供相应的竖向抗压、抗拔和抗倾覆等力,风机基础受力状态远比其他高耸结构基础的复杂,需采用桩基础进行深入地层处理以保证整体风机的稳定可靠,在满足上部结构荷载要求的前提下,采用适宜地基建设条件的型式简单、施工难度不大、造价较低的风机基础的设计尤为重要。

Due to the particularity of the high-rise structure of wind turbine to the architectural design requirements,the wind turbine tower is high,the base area is small,and the wind turbine engineering load is special.When the natural foundation can not provide the corresponding vertical pressure,pull and overturning forces,the force state of the fan foundation is far more complex than that of other high-rise structural foundations,and it is necessary to use the pile foundation for in-depth stratigraphic treatment to ensure the stability and reliability of the overall fan.Under the premise of satisfying the superstructure load,it is very important to design the fan foundation with simple type,little difficulty and low cost.
