Overview

Observational analysis shows tunnel construction under high-stress soft rock affects support structure stability, indicating new design methods are needed.

Key Points

  • Overall stability of the support structure is thoroughly assessed through numerical simulations and field measurements.
  • Results highlight the importance of mechanical behavior in evaluating the safety of tunnel support systems under high-stress conditions.
  • Analysis incorporates geological conditions and their effects on the surrounding rock pressure to improve construction methodologies.
  • The proposed calculation method aims to enhance the reliability of pressure design values, leading to safer tunnels.
