Cooperative supporting effect of intermediate bridge and inner dump on slope in adjacent open-pit mining area [PDF]

Scientific Reports
To solve the problem of dynamic demolition of intermediate bridges, this study investigates the calculation method for slope stability under the synergistic support effect of the intermediate bridge and the inner dump. Based on a constructed mechanical model of the intermediate bridge and the inner dump, and using the Mohr-Coulomb shear strength theory
