三维全断面自动扫描技术在隧道施工中的运用

A Brief Discussion on the Application of 3D Full-face Automatic Scanning Technology in Tunnel Construction

结合张吉怀高速铁路项目工程,阐述了三维全断面自动扫描技术在隧道施工中的应用。该技术能够有效地控制隧道超、欠挖,隧道初支、二衬混凝土方量,确保隧道开挖、初支及二衬断面均满足设计要求。该技术为今后类似工程施工提供一些可借鉴的经验。

Combined with Zhangjiajie-Jishou-Huaihua high-speed railway project,the application of 3D full-face automatic scanning technology in tunnel construction is expounded,which can effectively control the overbreak,underbreak,primary support and secondary lining concrete volume of the tunnel,and ensure that tunnel excavation,primary support and secondary lining section meet the design requirements.It also provides some reference experience for similar construction in the future.
