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.
