Excavation Damage Zone at High Depths: Field Cases and Coupled Analysis
One of the challenges of the modelling of hard soils and soft rocks is the precise reproduction of the Excavation Damage Zone (EDZ) around openings. Characteristics of the EDZ are indeed affected by both fissuration and fracturation, which requires the consideration of a mechanical model based on coupled damage-plasticity. In this abstract, the performance of a composite model developed by Vaunat & Gens [1] for such a purpose is tested by comparison with a large-scale field tests carried out in the Underground Research Laboratory of Meuse/Haute Marne (Callovo-Oxfordian formation, see Armand et al. [2]; Su [3]).
