用沉降监测结果指导建筑物的纠偏施工

Subsidence Monitoring Results with the Guidance of Corrective Buildings Construction

用基底掏土法对某7层砖混建筑物进行纠偏,对基础沉降进行密集监测。通过监测结果确定纠偏施工的取土量,施工节奏和施工速度等,有效控制了纠偏施工期间基础的挠曲变形,保证结构原有裂缝在纠偏期间不再发展,使建筑物纠倾后倾斜值小于9 mm。

Rectification of a seventh buildings used the indigenous basement,on the basis of settlement for intensive monitoring. Monitoring results through effective control of the corrective construction period based deflection, Guarantee cracks in the structure of the original development no longer corrective period, Correcting the building tilted after the dumping of less than 9 mm.
