Elastoplastic Semi-Analytical Solution for Deep Tunnels in Strain-Softening Rock Mass Considering Intermediate Principal Stress and Dilation Behaviour
Reliable estimation of squeezing deformation in deep soft-rock tunnels requires an elastoplastic formulation that can capture the post-yield response of the surrounding rock. However, existing theoretical approaches rarely account for the variation in intermediate principal stress associated with the evolution of dilat...
