Numerical solution for circular tunnel excavated in strain-softening rock masses considering damaged zone
Abstract Despite the extensive investigation on the stress and displacement distributions in tunnels, few have considered the influences of the damaged zone around a tunnel on the strength and stiffness parameters of the surrounding rock, including the gradual variation in the damaged factor D and d...
