Description
| - Although capable of addressing a number of important facts, such as the supporting effect of soil in the longitudinal direction of the tunnel and its inherent creep behavior, the accuracy of convergence confinement method is strongly affected by practical experiences of the designer. It is therefore still of considerable interest to improve the modeling phase whilst keeping its simplicity. Such a goal can be successfully achieved by combining the numerical analysis with in-situ measurements. Particularly, taking advantage of convergence curves in the longitudinal direction constructed during excavation, both in front of and behind the tunnel heading, it is possible to extend the general formulation into 3D whilst maintaining the two dimensional format of the finite element mesh as demonstrated in this contribution. The original formulation is now being extended to account for inelastic deformations in the context of exponentially decaying convergence curves.
