Measurement Method of High-rise Building Foundation Settlement Based on 3D Laser Scanning

文中结合平衡理论,确定地基沉降引起的水平扰动区范围,再提取地基沉降散射信息构建干涉图,根据实际地形特点,分析水平沉降的几何关系,获取高层建筑物地基沉降测量值。结果表明,所提方法得出的地基沉降测量值,最大绝对误差仅为1.52mm,满足沉降测量要求。

Based on the equilibrium theory,the range of horizontal disturbance caused by foundation settlement is determined,and then the scattering information of ground settlement is extracted to construct an interferogram.The geometric relationship of horizontal settlement is analyzed based on the actual terrain characteristics,and the measured value of foundation settlement of high-rise buildings is obtained.The experimental results show that the maximum absolute error of the measured value of foundation settlement obtained by the proposed method is only 1.52mm,which meets the requirements of settlement measurement.
