摘要
无张力灌注桩基础是一种新型的风机基础型式,特别适用于湿陷性黄土的地质条件,相对于传统基础,优化了结构型式、降低了造价。结合红寺堡风电场风机基础设计,通过有限元分析的方法,建立无张力灌注桩风机基础的有限元分析模型,对极端工况下基础的应力、位移、地基应力与沉降等进行了计算分析,为完善风机基础结构设计提供了依据,可供同类地质条件下风机基础结构的优化设计参考借鉴。
The tension-free bored pile is a new type of wind turbine foundation, which is suitable for collapsible loess. The structural form of the foundation is optimized and the cost is saved compared with the conventional foundation. By combination of the design of wind turbine in Hongsibao wind farm, a FEM analysis model of the tension-free bored pile of wind turbine is estab-lished. The stress, displacement, stress and settlement of foundation are calculated under extreme condition, which provides ref-erence for the perfection of the structural design of wind turbine foundation.
