监控量测技术在暗挖单洞重叠隧道中的应用

Application of the monitoring techniques adopted in overlapped single-cell tunnels

深圳地铁一期工程3C标段(国-老区间北段)暗挖单洞重叠隧道穿越了高层建筑物及交通主干道,环境条件复杂,地质条件差,高跨比大(近似为2),结构稳定性差,施工难度大,文章主要论述了施工监测在信息化施工中的重要作用。

The overlapped single - cell tunnels on the north Guo - Lao section of Shenzhen metro passes through underneath high buildings and traffic trunks. The environment is complex and the geologic condition is poor. The height to span ratio of the tunnel is large （ approx. 2） and the structure stability is also bad. The paper introduces the application and the importance of the monitoring techniques adopted in the observational construction of the tunnel.
