【Abstract】 After 4 month haul work, the inclination amount of a 28 - story building has been reduced from 542mm to 148mm and meets the requirements of the national specification. This paper introduces the selection of schemes for the rectification of this building and its technical achievements. At the same time, the design and construction of steel tube high-pressure grouting pile for ground stabilization are presented as well. By analyzing the cause of inclination, the calculation method of anti-overturning moment the structural measures for developing anchor moment and the theoretical calculation high jetting-pressure are put forward. Finally, the calculation of inclination rectification and anti-overturning of high-rise building are summarized. In addition, the feasible construction experience for inclination notification and anti -overturning are recommended as well.更多还原
