摘要: 大跨度钢结构安装施工存在施工精度高、钢构件受温度影响大、整体变形控制难等缺点。传统的大跨度钢结构安装施工主要通过全站仪对钢结构关键节点进行测量控制。该方法测点较少,对钢结构整体变形掌握不够全面,往往导致安装后钢结构在几个主要构件与最初设计模型吻合度较高,而在没有测点控制的位置存在较大误差,这种较大的安装误差往往会影响整个钢结构的使用寿命。为了更加准确地获取钢结构施工质量与设计偏差,本文提出了一种基于三维激光扫描与建筑信息模型(BIM)的对比分析方法,以检查钢结构模型的施工质量。首先,通过三维激光扫描方式获取施工后整体钢结构的三维点云数据,并进行去噪(从背景点云中分离);然后,将BIM模型与分离后钢结构点云进行对比分析,快速获取钢结构杆件的偏差值;最后,以援白俄罗斯国家足球体育场钢结构施工项目为例,通过本文方法快速获取钢结构与设计BIM模型偏差,计算施工后钢结构点云与设计BIM模型的偏差量。结果显示,该方法可有效检查出钢结构施工是否满足设计要求,有效保障钢结构施工,为钢结构施工质量检查提供了一种新的解决方案。

Abstract: The installation and construction of large-span steel structures face the disadvantages such as high construction precision requirements,significant influence of temperature on steel components,and difficulty in controlling overall deformation.In traditional installation and construction of large-span steel structures,the total station is mainly used to measure and control the key nodes of the steel structure.This method has fewer measuring points,and the understanding of the overall deformation of the steel structure is not comprehensive enough.As a result,after installation,the steel structure often has a high degree of coincidence with the original design model at several main components,but there are large installation errors between the positions without measuring point control and the design model.Such large installation errors often affect the service life of the entire steel structure.In order to obtain the deviation between the construction quality of the steel structure and the design more accurately,this paper proposes a comparative analysis method based on 3D laser scanning and BIM to detect the construction quality of the steel structure model.Firstly,the 3D point cloud data of the overall steel structure after construction is obtained through 3D laser scanning,and the point cloud of the steel structure is denoised (separated from the background point cloud).Then,the BIM model is compared and analyzed with the point cloud of the separated steel structure,and the deviation values of the steel structure members can be quickly obtained.Taking the steel structure construction project of the Belarus national football stadium as an example,this paper quickly obtains the deviation between the steel structure and the designed BIM model through the proposed method,and calculates the deviation amount between the point cloud of the steel structure after construction and the designed BIM model.The results show that this method can effectively check whether the steel structure construction meets the design requirements,effectively guarantee the construction of the steel structure,and provide a new solution for the quality inspection of steel structure construction.
