Numerical Investigation of the Stability of High and Steep Rock Slope Reinforced with Rock Bolts
Excavation-induced unloading alters the stress distribution and support demand in high and steep rock slopes. This study investigates a rock slope near the mainline toll station of the Xiangyang–Yichang Expressway. A FLAC3D model simulates seven-stage excavation. Displacement, plastic-zone distribution, factor of safet...
