以代县风电场工程为例，结合该工程场地的地质情况，对传统圆形扩展基础与岩石锚杆风机基础在不同荷载工程下的承载力进行了复核计算，通过对比分析，指出该工程采用岩石锚杆基础安全性高，经济合理且可以缩短施工工期。%Taking the wind power field engineering of Dai county as an example,combining with engineering field geology conditions,the paper re-check calculation of the foundation bearing capacity under various loading conditions of traditional circle expanding foundation and rock-bolt wind power foundation. Through comparative analysis,it points out that the application of rock-bolt foundation in the engineering has various ad-vantages,such as high safety,economic and rational,and shortening construction duration.
