Un modèle homogénéisé pour le boulonnage du front de taille des tunnels: simulation d'essais en centrifugeuse
The homogenized constitutive model developed by the ENPC for reinforced rock or soil masses has been introduced in the finite element code CESAR-LCPC and used for the simulation of centrifuge tests carried out to study the behavior of a tunnel face reinforced by bolts. The software correctly reproduced the measured deformations and makes it possible to study the influence of various parameters of the reinforcement. Moreover, the reinforced zone is treated in the mesh like a homogeneous zone, without discretization of the inclusions, which significantly reduces the time required by the preparation and execution of computations. The homogenized model should however be improved to get better results in the situations where the slip between the ground and the inclusions becomes dominating.
