Analysis of Surrounding Rock Pressure of Deep Buried Tunnel considering the Influence of Seepage
Geofluids, 2022 This paper takes the surrounding rock of deep tunnel as the research object and considers the action mechanism under the influence of seepage. Based on the Mohr-Coulomb criterion, the stress mechanism of surrounding rock of deep buried tunnel is analyzed by a convergence constraint method.
