摘　　要：为了满足长大隧道快速、安全施工的需求,通过分析隧道周边围岩的变形规律,提出了一种基于全站仪自由测站的隧道围岩收敛非接触监测的新方法。与传统的监控量测手段相比,新方法不仅能适应恶劣的洞内测量环境,达到及时反馈围岩收敛变形信息的目的,而且能够满足相关规范的精度要求,为隧道监控量测开辟了新的途径。To satisfy the requirements of fast and safe construction of long-and-large tunnels, this paper puts forward a new method of non-contact monitoring for tunnel surrounding rock convergence based on free station of a total station, by analyzing the deformation rule of rock around the tunnel. Compared with the traditional monitoring measurement methods, the new method not only can adapt to poor measurement environment inside the tunnel, to achieve the purpose of timely feedback, but also can meet the accuracy requirements of the relevant specifications, so it opens up a new way for tunnel monitoring measurement.
