Analysis and Control the Surface Settlement of Tunnel Excavation

Abstract:

Combined with the station of Maritime University ~ High-tech Zone tunnel project, this paper analyzes each section of the measured data on the spot to determine the surface subsidence. Research results show that the soil geological conditions of different effects on the subsidence are obvious, but shapes which formed by the settling tank are similar. Meanwhile, combining the construction of advanced small pipe grouting and shotcreting concrete technical measures, the surface subsidence control of the project abides by the surface subsidence rule of the shallow tunnel construction and deformation control.
