| 摘 要： | 以金凤隧道为例介绍了隧道监控量测的目的和意义、内容和方法,并对监测数据进行了分析。结果表明隧道在开挖期间围岩周边收敛、拱顶沉降、钢支撑内力、围岩位移等监测指标随时间的变化规律基本一致,都经历了加速、稳定、再次加速、最终稳定四个阶段,稳定值均在规范要求的范围内,说明隧道初期支护合理,可安全进行二衬施工。

| Abstract: | Taking the Jinfeng tunnel as an example,the purposed,content and technology of monitoring measuring are introduced,and monitoring data are analyzed.The results of measurement show that： surrounding rock convergence,arch apex settlement,stress of steel support,rock body displacement are in the range of specification;the variation law changing with time is consistent,through the acceleration,stability,accelerate again,final stability four stages.Above all showed that the support design in the Jinfeng tunnel were safe. |
