摘要： 风机基础承载能力提升对保障风机安全运行与风电效率充分发挥具有重要的作用。针对常见的基础环式风机，开展基础钢环与混凝土锚固效果的拉拔试验，研究基础钢环在设置端板和横肋等不同组合状态下，基础环锚固力学特性和破坏特征。试验结果表明：对于风机基础混凝土应力状态，设置横肋结构整体优于单独设置端板结构；在风机基础中同时设置端板和横肋结构，可充分发挥端板构造保护效果，亦可显著提高风机基础的极限抗拔承载能力。研究成果可为相关风机基础工程的设计和施工提供技术参考。

Abstract: The improvement of wind turbine foundation bearing capacity plays an important role in ensuring the safe operation of wind turbines and wind power efficiency. The pull-out test of the anchoring effect between the foundation steel ring and concrete was carried out to study the mechanical properties and failure characteristics of the foundation steel ring anchorage under different combinations of end plates and transverse ribs. The test results show that for the stress state of the concrete of the wind turbine foundation, the transverse rib structure is better than the end plate structure. The end plate and transverse rib structure are set in the wind turbine foundation at the same time, which can give full play to the protective effect of the end plate structure and significantly improve the ultimate bearing capacity of the wind turbine foundation. The research results can provide a reference for the design and construction of relevant wind turbine foundation project.

Key words: wind turbine foundation, foundation ring, end plate, transverse rib, pull-out test
