Causes of inclination of a high-rise residential building and relevant inclination-rectifying and reinforcement technology

Based on the inclination-rectifying and reinforcement of a thirty-storey residential building, the relevant inclination-rectifying measures and control technology are introduced after analyzing the causes of its inclination. In order to ensure the safety, stability and linear structure of inclined building, this project first adopts the combined inclination-rectifying reinforcement means of “major soil-digging and minor anchor-pressuring”, and brings forward many control technologies such as stress control, fine-tuning by anchor-pressuring and deformation control and so on, and thus scientific and reasonable construction procedures are prepared so as to guarantee successful implementation of inclination-rectifying and reinforcement of the high-rise building. The inclination rate of the building returns to 0.89 ‰ from 2.61 ‰ , meeting the national related standards and practical requirements. This project has created a new national record of inclination-rectifying buildings in the building height (97m) and the number of building floor (30 floors), and fills in the gap for the implementation of inclination-rectifying of high-rise buildings located on the weathered mudstone, complex foundation and deep foundation. It will be useful for rectifying inclined high-rise buildings.
