Analysis of the influence factors of wind turbine foundations in wind power projects

风电场风机基础构造要求关系到风机基础设计的安全性和经济性。针对扩展式圆板基础,通过改变H1(基础变截面高度)、H2(基础边缘高度)、C(混凝土强度等级)、K(基床反力系数)、R1(基础外半径)的数值,分析基础控制内力和水平动态刚度的变化趋势和规律,提出对规范部分条款的执行建议,从而实现对风机基础结构设计的优化。

The structural requirements of wind turbine foundations in wind power projects are related to the safety and economy of wind turbine foundations design.In this paper,for the extended circular plate foundation,by changing the value of H1(variable section height of foundation),H2(edge height of foundation),C(concrete strength grade),K(Coefficient of subgrade reaction),R1(foundation Outer radius),analysis of the change trend and rule of the foundation control internal force and horizontal dynamic stiffness,the implementation suggestions for some provisions of the specification are proposed,so as to achieve the optimization of the design of the fan foundation structure.
