摘要
为解决基坑在随机车辆荷载影响下三维整体变形监测困难问题。以天津一汽大众冲压车间某大型基坑为依托,采用BIM结合三维激光扫描技术,提出点云逆向生成BIM模型再与后期点云模型进行平台融合和误差分析的方法。掌握了基坑三维整体变形的情况,指导现场安全施工,对于BIM结合三维激光扫描技术的集成化应用具有一定的指导性意义。
In order to solve the difficultly in three-dimensional integral deformation monitoring of foundation pit under the influence of random vehicle loads,based on a large foundation pit in Tianjin FAW Volkswagen stamping workshop,BIM combined with three-dimensional laser scanning technology was adopted to propose a method for platform fusion and error analysis between point cloud reverse-generated BIM model and a later stage point cloud model.It is of guiding significance for the integrated application of BIM combined with three-dimensional laser scanning technology to grasp the situation of three-dimensional integral deformation of foundation pit and guide the safe construction on site.
