摘　　要：基于大量隧道监控量测数据的统计分析,确定了隧道净空收敛值的影响因素,得到了隧道净空收敛值的主成分因子和权,根据概率统计理论提出了围岩动态分级的修正公式,工程应用结果表明,基于监控量测的隧道围岩动态分级方法与隧道开挖的实际情况十分吻合。This paper determines the influence factors of tunnel convergence value clearance and obtains the tunnel convergence value clearance of principal component factor and power based on the statistical analysis of a lot of tunnel monitoring measurement data. The authors put forward correction formula of dynamic classification of surrounding rock according to the theory of probability and statistics. The results show that the classification method of the tunnel surrounding rock based on the real-time monitoring measurement is quite coincident with the actual situation of tunnel excavation in engineering applications.
