某高层住宅楼倾斜原因及纠倾加固技术研究

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

  • 摘要: 在正确分析一 30 层高住宅楼倾斜原因的基础上,对该楼纠倾加固工程采取的纠倾加固措施以及控制技术进行了针对性的研究。为确保该倾斜建筑物安全、平稳、线性的回归,本工程通过首次采用“基底掏土为主,锚索加压为辅”的组合纠倾方法,对应力控制、锚索加压调控及变形控制等多重纠倾控制技术进行深入的研究,而后制定科学合理的施工工序,最终保证了该高层建筑物纠倾加固工程的成功实施,大楼倾斜率由纠倾前的 2.66‰ 回归到 0.87‰ ,满足了国家相关规范及正常实用要求,本工程在纠倾高度( 97 m )及层数( 30 层)方面,刷新了国内高层建筑物纠倾纪录,填补了在强风化泥岩、复杂地基、深埋基础中实施双向纠倾的空白,对高层建筑物的纠倾具有很高的借鉴价值。

     

    Abstract: 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.
