The prediction and control of the ground surface settlement and deformation are ones of the most crucial problems in all environmental damages induced by metro tunneling excavation. The metro tunnels are usually excavated and constructed as double tube parallel tunnels; and the space between the double tunnels is generally short distance. The ground surface settlement and deformation induced by two staged tunneling is usually overlapped and is also hard to predict consequently. Based on the stochastic medium theory

the formula for predicting is modified; it is reality to predict the ground surface settlement

lateral displacement

inclination and curvature induced by double tube parallel tunneling excavation; a new software system is developed to predict ground surface settlement and deformation induced by urban tunnel excavation. Two cases study for the double tube parallel tunneling projects are carried out to verify the validity and reliability of the proposed theoretical approaches and software system.
