Triaxial mechanical behavior and damage evolution of stratified cemented tailings backfill incorporating an enhancement layer

Key Points

• Damage evolution indicates significant changes in triaxial behavior of backfill mixtures, with layer enhancements promoting stability.
• Peak strength capacity was affected by the incorporation of enhancement layers, showcasing notable differences during testing.
• Observational analysis involved subjecting cemented tailings backfill to triaxial tests, systematically examining mechanical responses.
• Improved triaxial behavior highlights the importance of layering, indicating potential applications in mining and civil engineering.
