Monitoring Study on Drift Deformation by Shield Tunnel
Take the one-third of the allowable values as the basic value. The control standards of the ground subsidence is 30 mm, and the control standards of the ground swell is 10 mm. Take one typically stretch of sites as research object by the buried depth and plane disposition condition. Take ten sections and the kilometer post. Consider 52 contents as of an analysis. The maximum subsidence is mostly kept within 13 mm. The monitoring data of each lateral section are certain differences because of the different gemological conditions, the water quality, soils covered and so on. When the shield drives off the monitoring section, the subsidence is about 6 mm ∼ 16 mm and 50% of the total subsidence. The main subsidence appears after the shield tail pass out for sand.
