摘要
为了掌握隧道施工过程中隧道周边收敛以及围岩内部位移的变化规律,用SW-Ⅵ收敛计、三点位移计分别对隧道初期支护和二次衬砌阶段进行了位移监测,并对2个阶段所采集的数据进行了分析。分析结果表明各测试段位移平均速率均小于基本稳定判别标准,说明隧道支护结构工作状态良好。
In order to grasp the changing regulations of circumference convergence and internal displacement of tunnel, the displacement monitoring of initial support and secondary lining is done using SW-Ⅵ convergence gauge and three-point displacement meter. The results show that the average velocity of testing sections is less than basic stabilization criterion, and reveals the working status of tunnel support structure is better.
