摘要
依托北京地铁17号线工程,探讨监控量测技术在地铁隧道施工中的应用。对横通道特定断面采取监控量测,并结合现场掌子面情况对围岩进行有效分析。结果表明:施工完成后,平移通道围岩变形不大,基本处于稳定状态;地表沉降、拱顶沉降、周边收敛最终趋于稳定;钢拱架变形基本稳定,后期应继续对地表沉降、周边收敛等进行观测。
Based on the project of Beijing metro line 17,the application of monitoring and measurement technology in subway tunnel construction is discussed.The monitoring of the translation channel are set,and the monitoring results are also analyzed.The surrounding rock is effectively analyzed in combination with the situation of the tunnel face on site.The results show that after the completion of construction,the surrounding rock of the translation channel has little deformation and is basically in a stable state;surface settlement,vault settlement and peripheral convergence finally tend to be stable;and the deformation of steel arch frame is basically stable,and the surface settlement and peripheral convergence should be observed in the later stage.
