提高风机基础环锚固性能的措施研究

Measures to Improve the Anchorage Performance of Foundation Rings of Wind Turbines

风机基础环锚固性能的好坏直接影响着风机的安全运行。结合实际工程的探讨表明,增加基础环埋置深度和下法兰宽度以及加强基础环构造措施对基础环的锚固性能有显著提高,增加基础环穿孔钢筋数量、提高混凝土施工质量和做好基础密封防水措施也有利于提高基础环的锚固性能。

The anchorage performance of the foundation ring will directly affect the safe operation of wind turbines.Analysis of practical engineering projects show that the anchorage performance of the foundation ring can be significantly improved by increasing its embedding depth and the width of the lower flange,and strengthening the foundation ring structure.Also,increasing the number of the perforated steel bars in the foundation ring,improving the concrete construction quality and adopting effective seal and waterproof measures in the foundation are also helpful to improve the anchorage performance of the foundation ring.
