摘　　要：针对传统的隧道施工监测方法工作效率低、精度低等问题,在充分调研后,引入了先进的三维激光扫描新技术进行隧道监测;在隧道建设过程,成功预警局部大变形、断面侵限、局部偏压等情况,并为相关病害处置、工法变更、设计变更提供了有力数据支撑,为隧道安全施工提供了有效保证。In response to the problems like low work efficiency,low accuracy in traditional tunnel construction monitoring methods,the advanced 3D laser scanning technology is introduced for tunnel monitoring after the thorough research;during the tunnel construction process,successful early warnings are given for local large deformation,cross section intrusion,local bias and other situations,so as to provide strong data support for relevant disease treatment,construction method change,and design change,and provide effective guarantee for safe tunnel construction.
