摘要:杭州西站屋盖钢结构整体为双曲造型，体量较大，常规监测方法无法满足现场快速、全面的结构变形监测要求。为实现杭州西站项目高精度、高效率和全过程的变形监测，采用三维激光扫描获取结构建造全过程的点云数据，将点云数据处理后与BIM模型配准，完成单构件偏差分析、施工过程和成形态结构偏差分析，实现建造全过程的变形监测。监测结果与全站仪测量数据对比表明，三维扫描变形监测与全站仪测量的数据值及标准差基本一致，数据波动较小，监测结果稳定，适用于大型空间钢结构项目建造全过程的变形监测。
Abstract: The steel hyperbolic roof of Hangzhouxi Railway Station is of large volume. The conventional monitoring methods cannot meet the requirements in terms of speed and comprehensiveness. In order to realize high-precision, high-efficiency, and whole process deformation monitoring of Hangzhouxi Railway Station, 3D laser scanning is used to obtain the whole-process point cloud data. The processed point cloud data is registered with the BIM model to analyze the deviation of single component, construction process and morphological structure, so as to realize the whole-process deformation monitoring. The comparison with the measured data of the total station shows that the 3D scanning deformation monitoring is basically consistent with the data value and standard deviation measured by the total station, the data fluctuation is small, and the monitoring results are stable. It is suitable for the whole-process deformation monitoring of large space steel structure projects.
