Overview

Analysis reveals karst cavities amplify tunnel deformation, suggesting a composite lining can improve safety.

Key Points

  • Local deformation increased significantly near karst cavities, showing a marked effect on tunnel safety.
  • The finite element model assessed the mechanical behavior under karst influences, leading to vital safety insights.
  • Observational analysis of tunnel structures highlighted critical stresses due to nearby karst features.
  • The findings emphasize the importance of karst positioning for effective tunnel engineering, with potential implications for design.
