Numerical simulation of the EDZ and of the self-healing around an excavation

The modelling of the excavation process and the strain localization prediction along the process has been performed using the finite strain Finite Element Code Lagamine, with the constitutive law CLoE. A special modelling procedure was designed, taking into account the progressive excavation as a process in time, the placement of a lining behind the excavation front, the existence of a over-excavation with respect to the lining dimensions, and the hydromechanical coupling. The results are consistent with the site observations, especially the localization are predicted. Further refinements would be necessary to reduce some discrepancies observed with respect to site data.
