Three-Dimensional Stability Analysis of a Tunnel Roof at Varying Burial Depths in Saturated Hoek–Brown Rock Masses
This study investigates the stability of three-dimensional (3D) tunnel roofs with varied burial depth in saturated rock strata following the Hoek–Brown (HB) failure criterion. Within the framework of limit analysis, a 3D kinematic collapse mechanism for tunnel roofs, incorporating the existence of pore water pressure,...
