摘　　要：为了研究风电基础钢环与混凝土的粘结机理,通过简化模型的拉拔试验,分析了型钢与混凝土粘结应力沿锚固长度的分布规律.通过与现行规范钢筋锚固长度的计算方法比较,风电基础钢环锚固长度可参照现行《混凝土结构设计规范》光圆钢筋锚固计算方法,为风电基础设计提供了实验依据,可供相关设计人员参考.In order to research the distribution of the bond stress between steel ring and concrete along the embedded length, the paper studies pullingout experiment of wind generating foundation simplified model and the distributions of bond sress betweent steel ring and concrete along the embedded length are ana lyzed. By comparison, the method of current specifications calculation of plain round bar can be used as cal culation of the embedded length of steel ring which provides a reliable experiment reference for the design of wind generationg foundation.
