| 摘 要： | 以某大跨山岭公路隧道的施工为背景并针对岩质隧道掘进过程中的围岩稳定性问题。运用数值模拟和现场监测等相结合的方法,首先对隧道发生局部塌方范围在内的区段进行施工模拟,之后依据相关规范,对围岩塌方区域的现场实测数据进行分析,并将模拟结果和监测数据进行了对比。分析结果表明,在隧道塌方前,围岩已处于不合理的受力形态,同时实测拱顶沉降数据也已经达到了变形预警值,数值模拟和监控量测均较好的反映和预测了隧道塌方问题。

| Abstract: | Based on the construction of a large-span mountain highway tunnel,the stability of surrounding rock during the excavation of rock tunnel is studied.By using the method of numerical simulation and on-site monitoring, the construction simulation is carried out in the section including the local collapse area of the tunnel, and then the field measured data in the surrounding rock collapse area is analyzed according to the relevant specifications,and the simulation results are compared with the monitoring data.The analysis results show that before the tunnel collapse,the surrounding rock has been in an unreasonable stress state, and the measured vault settlement data hasreached the deformation warning value. Both numerical simulation and monitoring measurement can better reflect and predict the tunnel collapse problem. |
