摘要
研究了隧道监控量测结果在围岩动态分级中的应用.通过对隧道监测数据的统计分析,得出了对围岩动态分级具有意义的指标和各级围岩所对应的各指标的数值范围,用以指导施工阶段的隧道围岩动态分级、隧道的反馈设计和施工过程中的预测预报.实例证明,准确的隧道监测数据可以进一步完善和优化围岩分级,提高围岩分级的可靠性,为隧道围岩动态分级提供了一条新的途径.
This article studies the application of the tunnel monitoring in surrounding rock mass dynamic classification. By statistical analysis about tunnel monitoring data, we obtain the significant gauging targets for tunnel surrounding rock mass dynamic classification and the range of targets value with different rank in surrounding rock mass. All these results can provide instruction for dynamic classification of tunnel surrounding rock mass in construction state, feedback design of tunnel and forecast in tunnel construction. The example shows that accurate tunnel monitoring data can further improve and optimize surrounding rock mass classification, enhance the reliability of surrounding rock mass classification and provide a new approach for the tunnel surrounding rock mass dynamic classification.
