摘　　要：风电机组运行时产生较大的弯矩,风机基础底部会出现较大的附加应力为负的区域,GB50007—2011《建筑地基基础设计规范》附录K仅给出了圆形面积上均布荷载和三角形荷载作用下的附加应力系数。为此,论文以某风电项目为研究对象,分析了基底附加应力分布图,提出一种将不规则的附加应力区域简化为矩形区域的办法,从而可以通过查询角点附加应力系数计算沉降变形和倾斜率。Wind turbine generate large bending moments during operation,large areas with negative additional stress will appear at the bottom of the wind turbine foundation,the GB 50007—2011 Code for design of building foundation appendix K only give the additional stress coefficients for uniformly distributed loads and triangular loads over on circular area.Therefore,this article takes a wind power project as the research object,analyzes the distribution diagram of the additional stress of the base,and proposes amethod to simplify the irregular additional stress region into a rectangular region,so that the settlement deformation and inclination rate can be calculated by querying the additional stress coefficient of corner points.
