摘要: 提出了一种带朵纠倾掏土孔的既有建筑纠倾新方法,给出了带朵纠倾孔孔壁最大应力的近似计算公式,用数值计算方法验证了近似公式的适用性。新方法相对于传统圆形掏土孔方法能更好地实现建筑纠倾工程的精确可控、快速纠倾、避免过倾。当大孔半径与小朵孔半径之比在1$\sim $6范围时,纠倾效果较好。

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$\sim$6, the performance is good.

Key words: digging hole|stress concentration|digging soil rapidly|controllable inclination rectification
