Overview

Observational analysis reveals critical parameters affecting support design in tunnel groups, indicating the importance of burial depth and reinforcement ratio.

Key Points

  • Support design must consider deformation characteristics of surrounding rock to ensure safety.
  • Findings indicate that reinforcement ratio and secondary lining thickness are crucial for bearing capacity.
  • Numerical simulations and field tests helped assess ground stress and reaction under varying conditions.
  • Recommendations for support timings are provided for various rock grades and burial depths to maintain structural integrity.
