Overview

Controlled-yielding design enhances support and reduces material costs in high-pressure tunnels, indicating improved safety.

Key Points

  • This research aims to explore the mechanical behavior of steel linings in high-pressure tunnel environments.
  • Developed an elastoplastic analytical solution for steel lining behavior.
  • Characterized mechanical responses during the plastic stage under internal pressure.
  • Analyzed the interaction between steel lining and surrounding rock.
  • The controlled-yielding design significantly increased the internal pressure capacity of tunnels.
  • Reduced the required thickness of steel lining under weak rock conditions.
  • Enhanced load-sharing ratio of surrounding rock, fully utilizing its bearing capacity.
