介绍了某6层框架剪力墙结构房屋抬升法纠偏的整个过程。通过在地基压入锚杆静压桩提供反力,在筏板上植筋架设反力梁,在桩顶设置千斤顶,辅助地下车库堆载加压的抬升纠偏方法,成功地完成了房屋的纠偏,使得房屋的倾斜率由5.5‰变为2‰以内。在纠偏全过程采用高精度测量机器人实时跟踪监测筏板基础的沉降值,是房屋成功纠偏的保证。

T he whole deviation-rectifying and reinforcing treatment process of a 6-story framework shear wall structure building w as introduced in this papaer. As counterforce is generated by installing anchored static-pressure piles in the foundation,counter-force beams and jacks are set respectively at the embedded steel bars of the raft and at the pile tips,so as to heap loading on the underground garage and coordinate the pressure against it. T hanks to such treatment,the leaning ratio of the building declined from 5. 5‰ to 2‰. High-accuracy measuring robot is used to monitor the settlement of the raft,which stands as the key to the success of the deviation-rectifying and reinforcing treatment of the building.
