内蒙古某风力发电机组基础优化设计探讨

摘要
根据风机基础的受力特点,分析了正常运行工况和极端荷载工况下,圆板式扩展基础和正八边形扩展基础的计算要点,同时通过计算数据说明两种基础形式在相同埋深和不同埋深情况下混凝土用量的变化规律,可供相关科研及设计参考.
China is very rich in wind power resources;and also develops wind power projects rapidly in recent years.As the special nature of wind energy resources,so part design standards are more stricter than relevant provisions in code foundation design of buildings because of uncertainty and particularity of loads applied on wind turbine-generator set foundations.According to the stress characteristics of the foundation,the key points of calculation of the round basis plate and regular octagon basis plate under normal operating conditions and extreme load operating conditions are analyzed.Especially,in the same depths and different depths cases needed the amount of concrete variation.Finally,a reasonable conclusion is drawn for referencee in the relevant research and design.
