三维激光扫描在超高层倾斜监测中的应用

Application of 3D laser scanning in super high rise building rilt monitoring

针对超高层倾斜监测传统方法中数据获取量少、成果展示不直观等问题。利用三维(3D)激光扫描仪对超高层建筑进行扫描,通过建立超高层核心筒模型,提取指定高度角点坐标,从而计算超高层倾斜率。以济南平安金融中心超高层建筑为例,通过三维激光扫描结果与全站仪实测结果的比较,验证了三维激光扫描在超高层倾斜监测中应用的可行性,此方法能够提高观测效率,为同类型项目实施提供了借鉴。

Aiming at the problems of less data acquisition and non-intuitive results display in the traditional methods of super high rise tilt monitoring.The three-dimensional(3D)laser scanner was applied to scan the super high-rise building.By extracting the point cloud data at the specified height,the corner coordinates of the core cylinder was obtained by using the least square rectangular fitting algorithm,so as to calculate the super high-rise tilt ratio.Taking the super high-rise building of Jinan Ping'an financial center as an example,through the comparison between the 3D laser scanning results and the total station measurement results,the feasibility of the application of 3D laser scanning in super high-rise tilt monitoring was verified.This method could improve the observation efficiency and provide reference for the implementation of similar projects.
