A coupled elastoplastic and visco-plastic damage model for hard clay and its application for the underground gallery excavation
The numerical modelling of the excavation of an underground gallery in hard clay has been discussed in current article. A constitutive model is proposed to describe poromechanical behaviour of the hard clay. The main features of the hard clay observed in laboratory and in-situ experimental investiga...
