DEM simulation of rock creep in tunnels using Rate Process Theory
J.G. Gutiérrez-Ch, S. Senent, P. Zeng , R. Jimenez Abstract The time-dependent (creep) behaviour of rocks affects the safety and stability of tunnels excavated in weak rocks and at great depths. Several theories have been proposed to simulate the creep deformation in rock; i.e., the progressive time-dependent damage that rocks (or other materials) exhibit under constant stress. However, most of these theories do […]
