Introduction,ion methods and the modern design tools based on the analysis of the ground support interaction. The principles of the convergence-confinement method are presented. The complexity of the tridimensional problem near the face is reduced to a plane strain problem by introducing the concept of a ..

The Convergence-Confinement Method for a Tunnel Driven in an Elastic Medium,ss are derived under the assumption of isotropic and anisotropic initial stress state. These analytical solutions are used for the application of the convergence-confinement method which permits to determine the support pressure and the corresponding radial displacement at the tunnel wall at the final equilibrium state.
