Deterioration characteristics of red beds lithological interface under water-rock interaction and its influence on tunnel deformation

Key Points

• Tunnel deformation is significantly influenced by the deterioration characteristics of lithological interfaces under water-rock interaction.
• Hydro-mechanical factors contribute to changes in geomechanical properties that affect tunnel stability over time.
• Analysis of rock samples reveals specific deterioration characteristics that inform tunnel design and safety measures.
• Study findings may enable better management of tunnel structures in similar geological conditions, improving safety and longevity.
