三维激光扫描与BIM技术在大型交通枢纽改扩建项目中应用

Application of 3D Laser Scanning Technology and BIM Technology in Large scale Transportation Hub Reconstruction and Expansion Project

探讨了三维激光扫描技术与BIM技术在大型交通枢纽改扩建项目中的优势与应用价值,并进行了应用思路分析。在此基础上,结合南京禄口机场T1航站楼改扩建工程实例,介绍了三维扫描站点布置、点云数据获取、三维逆向BIM建模等内容。经实践,验证了三维激光扫描技术与BIM技术在大型交通枢纽改扩建项目中应用的有效性。

The advantages and application value of 3D laser scanning technology and BIM technology in large-scale transportation hub reconstruction and expansion projects are discussed,and the application ideas are analyzed.On this basis,combined with the reconstruction and expansion project of T1 terminal of Nanjing Lukou Airport,the layout of 3D scanning station,the acquisition of point cloud data,the modeling of 3D reverse BIM,etc.are introduced.The aplication validity of 3D laser scanning technology and BIM technology in large-scale transportation hub reconstruction and expansion project is verified by practice.
