三维激光扫描与BIM技术在隧道超欠挖中的应用

Application of 3D laser scanning and BIM technology in over-under-excavation in tunnel

文中基于Revit等处理软件,给出了三维激光扫描技术与BIM技术结合应用于隧道超欠挖量测量计算的完整技术方案,结合具体工程建立了设计与实际三维模型图、断面图,计算了断面超挖量、欠挖量,通过与传统超欠挖方式对比,验证了三维激光扫描技术与BIM技术结合能够简化隧道超欠挖测量的流程,提高整体工作效率。

Based on Revit and other processing software,in this paper,the complete technical solution was gave combining with the 3D laser scanning technology and BIM technology for the measurement and calculation of over-under-excavation in tunnels.Design and actual 3D model drawings and cross-section drawings were established,and the amounts of over-excavation and under-excavation of the cross-section were calculated.It was verified that the combination of 3D laser scanning technology and BIM technology could simplify the process of the over-under-excavation measurement in tunnel by comparing with the traditional over-under-excavation method to improve the overall work efficiency.
