Abstract: This paper presents a FLAC3D finite difference model of the twin shield tunnels. The objective of the model is to obtain the surface settlement and soil mass movement during the tunnel construction. The settlement characteristics of single and double tunnels, the shield support time, distance to the shielding surface, grouting time and soil pressures on the deformation of the sounding soils are also investigated.

Key words: Shield Tunneling, Numerical Simulations, Surface Settlement, Lateral Displacement
