摘　　要：围岩监控量测等级技术是针对隧道围岩变形展开风险控制的一种管理技术。阐述了如何结合隧道围岩变形特征和施工安全性要求,应用监控量测等级技术合理地确定监控量测位移控制基准,划分Ⅰ、Ⅱ、Ⅲ、Ⅳ级隧道围岩位移管理等级并配套工程预防处理措施,建立了科学的等级管理制度;对现场围岩变形观察情况和量测数据进行分析,应用等级管理制度的工程措施实施变形风险控制,最终达到了降低和控制变形风险的目标。Surrounding rock grade monitoring measurement technology is a management technology for risk control of tunnel surrounding rock deformation. This paper expounds how to reasonably determine the displacement control datum of monitoring measurement based on the deformation characteristics and construction safety requirements of tunnel surrounding rock, as well as to divide the displacement management grades of tunnel surrounding rock into grade I, II, III and IV, and establish a scientific grade management system by matching engineering prevention and treatment measures, and analyses the observation and measurement data of surrounding rock deformation on site. Finally, the objective of reducing and controlling the risk of deformation is achieved by applying the engineering measures of grade management system to implement the deformation risk control.
