Stress relaxation tunnelling
Posted: Tue May 08, 2018 8:24 pm
i'm modelling a staged construction for a tunnel (NATM), during the excavation process i have to describe the stress relaxation (according to the convergence confinement method) but i don't find a way to introduce a stress distribution orthogonal to the curved line of the crown. I would like to know if there's a way to represent this behaviour in Code Bright. Many thank's for your help
