Abstract: |
This paper presents the validation of a novel constitutive model for shotcrete in a tunnelling project. The shotcrete model is based on elastoplastic strain hardening/softening plasticity and can account for time dependent strength and stiffness, creep and shrinkage. The validation of the model considers the deformation behaviour of both the primary lining and the surface as well as the time dependent stress strain behaviour of the shotcrete. The calibrated model has been used to simulate the behaviour of the tunnel structure during the excavation process numerically. Furthermore different approaches to model the shotcrete lining for design are applied and briefly discussed. |
