摘　　要：滇西地区隧道工程在施工过程中大变形问题突出,针对传统的隧道支护变形监测方法难以及时掌握变形情况、数据不准确等问题,文章基于大瑞铁路杉阳隧道施工工程,提出基于镭射线红外线监测技术的仰拱开挖中边墙位移连续性的监测方法,将红外监测系统设计与仰拱开挖参数相结合,现场实施效果表明,该技术相较于传统监测技术,能够实时掌握边墙位移变形情况;当变形数据异常时,可及时调整施工参数或采取加固措施,有效保障施工安全,为类似工程施工提供了重要参考。The problem of large deformation is prominent in the construction process of tunnel projects in western Yunnan.In response to the difficulties of traditional tunnel support deformation monitoring methods in timely grasping the deformation situation and inaccurate data,this article proposes a monitoring method for the continuity of side wall displacement in inverted arch excavation based on the construction project of Shanyang Tunnel on the Darui Railway.The infrared monitoring system design is combined with the parameters of inverted arch excavation.The on-site implementation effect shows that compared with traditional monitoring technology,this technology can real-time grasp the displacement and deformation of side walls;When the deformation data is abnormal,construction parameters can be adjusted in a timely manner or reinforcement measures can be taken to effectively ensure construction safety,providing important reference for similar engineering construction.
