An analytical solution for shallow buried tunnel reinforced by point anchored rockbolts

An analytical solution for the orthotropic semi-infinite plane with an arbitrary-shaped hole

“…Compared to problems of the infinite plane with the hole, problems of the semi-infinite plane with the hole present additional challenges due to the consideration of upper surface boundary conditions [12,13]. Verruijt [14,15] first used the conformal mapping technique in the complex variable function method to map a semi-infinite plane with a circular cavity in the physical plane to a circular ring in the image plane.…”

Coupled analytical solutions for circular tunnels considering rock creep effects and time-dependent anchoring forces in prestressed bolts

“…Using the finite element method, Qian and Zhou (2018) examined the deformation and failure of rocks under high in-situ stress in the underground cavern group of the Jinping I Hydropower Station, and discussed the mechanisms for the failure and overrun of some anchor bolts. Considering the interaction between the reinforcement system and the rock, Cai et al (2020) and Sun et al (2021) studied the evolutions of bolt anchoring force and rock stress and displacement through numerical simulations.…”
