结合工程实例,经过对施工现场监测数据包含地表沉降、拱顶沉降及隧道净空收敛数据的分析,研究了粉土地区浅埋暗挖隧道开挖支护过程及二次衬砌所引起的围岩变形与及地表沉降的规律,总结了施工过程中控制变形的具体工程措施。结论可为类似条件下工程施工和监测提供借鉴。
結閤工程實例,經過對施工現場鑑測數據包含地錶沉降、拱頂沉降及隧道淨空收斂數據的分析,研究瞭粉土地區淺埋暗挖隧道開挖支護過程及二次襯砌所引起的圍巖變形與及地錶沉降的規律,總結瞭施工過程中控製變形的具體工程措施。結論可為類似條件下工程施工和鑑測提供藉鑒。

In this paper, combining with engineering example and according to analysis monitoring data which include ground subsidence, vault settlement and tunnel clearance convergence data during the construction, it studied the process of excavation and support during tunnel construction of shallow-buried, deformation of surrounding rock by secondary lining and the laws of surface subsidence in silt area. And the specific control measures of deformation in the course of construction is also summarized, which could be treated as references for construction and monitoring of similar engineering.
