The Gaoloushan Tunnel in Longnan City, Gansu Province, China, frequently experiences rockburst disasters due to high in-situ stress. Managing rockburst in deep-buried tunnels remains a challenging issue. This paper employs RFPA (Rock Failure Process Analysis) software to establish a calculation mode...
