Analysis on Ground Deformation Caused by Tunnelling of Large-Diameter Tunnel Boring Machine
The large-diameter shallow buried tunnel is not advantageous for ground surface deformation control. It's necessary to make study and research on the ground deformation caused by the advance of TBM. In this paper, the ground surface deformation curve is obtained based on the deformation measured data during the excavation of TBM in the soft ground of Shanghai, and the parameters of excavation, including slurry pressure and volume of synchronized grouting that affect the ground deformation are discussed. In addition, a fitting method to estimate the ground loss is put forward, which reduces the experience dependence and enhances the reliability of peck formula. It is also very simple for practical application to estimate the ground deformation.
