Abstract: The ground subsidence is often observed during the shielded excavation of tunnels and excessive ground settlement will adversely affect the structural safety and the operation of the metro tunnels. This paper presents the factors that affecting the longitudinal deformation of the tunnel in the various stages of construction under different geotechnical conditions by the shielded excavation. The conclusions can be applied in the ground subsidence control.
