为了确定关虎冲隧道围岩在施工过程中的稳定性，针对关虎冲隧道典型断面的周边收敛、拱顶沉降和仰拱隆起等监测数据进行了整理和分析，并在此基础上对施工过程中隧道围岩的稳定性进行了判断。隧道监控结果表明，关虎冲隧道在施工过程中，各断面的周边收敛及拱顶沉降都是前期变化较快，后期变化缓慢，围岩变形基本稳定。分析方法对类似隧道工程的监控量测信息的合理应用具有参考意义。
為瞭確定關虎遲隧道圍巖在施工過程中的穩定性，針對關虎遲隧道典型斷麵的週邊收斂、拱頂沉降和仰拱隆起等鑑測數據進行瞭整理和分析，併在此基礎上對施工過程中隧道圍巖的穩定性進行瞭判斷。隧道鑑控結果錶明，關虎遲隧道在施工過程中，各斷麵的週邊收斂及拱頂沉降都是前期變化較快，後期變化緩慢，圍巖變形基本穩定。分析方法對類似隧道工程的鑑控量測信息的閤理應用具有參攷意義。

In order to evaluate the stability of surrounding rock in Guanhuchong Tunnel during construction, the monitoring data and measurement about peripheral displacement convergence, vault settlement and uplift of inverted arch were put together for analysis. It is shown that the peripheral displacement convergence and vault settlement change faster in the early stage of construction, then slow down at the later half stage of construction, resulting in the surrounding rock in a mostly stable condition. This analytical method may be of reference for future reasonable usage of monitoring and measurement data of similar tunnels.
