摘　　要：NODEXS77R70MT风机为国家风电研究检测试验基地第1台建设的风机机组,单机容量为1 500 kW,轮毂高度为70m。风机基础采用圆形钢筋混凝土扩展基础,除进行一般风机基础的各项结构计算外,还采用三维有限元进行了基础的本征频率和静态、动态刚度计算。风机基础在寒冷的冬季施工,在采取必要的施工措施后,可以满足相关技术要求。试验风机基础的设计和施工,取得了较好的社会、经济效果,并为该类型的风机基础积累了设计和施工经验。NODEX SS77 R70MT Fan is the first unit installed in national wind power study test site with unit capacity of 1 500 kW and hub height of 70 m.The foundation adopts circular reinforced concrete spread foundation.Except for structural calculation of general fan foundation,three-dimensional finite element method is also used for eigen frequency,static and dynamic rigid calculation.When the fan foundation is constructed in cold winter,it will meet with relevant technical requirements after necessary construction measures are taken.The design and construction have obtained good social and economic results,and accumulated some experiences for fan foundation of this kind.
