摘　　要：基于隧道施工实践,对隧道监控量测项目的设计、布置、监测频率等方面进行详细阐述。监控量测技术不仅可以对隧道内围岩和支护结构的变形变位进行实时监测,还可对隧道地表下沉、隧道周边位移及拱顶下沉进行监测,通过对测量数据的分析,可指导隧道现场施工,保证隧道施工安全。Based on the practice of tunnel construction, some aspects of tunnel monitoring measurement project like design, arrangement, monitoring frequency and so on are elaborated in detail. The monitoring measurement technology can not only pefform the real -time monitoring on the deformation and deflection of surrounding rock and supporting structure in the tunnel, but also monitor the tunnel surface subsidence, periphery displacement of tunnel and vault subsidence. Through the analysis on the measurement data, the tunnel site construction can be guided, so as to guarantee the safety of tunnel construction.
