浅谈基坑支护工程变形监测方案

Scheme Design of the Deformation Monitoring in the Foundation Pit Supporting Project

针对基坑支护围护结构顶部沉降与水平位移监测技术与变形方法进行研究。通过对基坑支护围护结构顶部沉降与水平位移监测数据进行分析,解算各监测点的累积沉降和总体位移变化量,从而及时掌握基坑的变形状况。根据监测点的变形限值标准,确定可能出现预警的变形点,并分析基坑不同部位发生沉降和偏移的原因。

Foundation pit support for the building envelope at the top of the settlement and horizontal displacement monitoring technology and methods of deformation. Through the excavation enclosure at the top of the settlement and horizontal displacement monitoring data analysis, calculate the cumula- tive settlement of all monitoring points and the overall displacement volume, and thus grasp the de- formation of foundation. According to the deformation limit of the standard monitoring to identify early warning of possible deformation point, and analysis of foundation settlement and migration occurred in different parts of the reason.
