Abstract: A method of the inclination rectification of digging hole of flower shape for rectifying the existing building inclination is proposed , and the approximate calculation formula for the maximum stress in the hole wall is obtained, and the applicability of this formula is verified by a comparison with the results obtained by the numerical method. The new method can make the inclination rectification much more controllable, accurate, and rapid and as compared with the traditional way, in addition, the back inclination is avoided. As the ratio of the large hole radius to the small flower shape hole radius is in the range of 1\sim6, the performance is good.
