Overview

Randomized trial investigates key parameters affecting tunnel construction efficiency in mountainous regions, suggesting enhanced techniques.

Key Points

  • This research aims to analyze key parameters and develop integrated techniques for mechanized tunnel construction using the drilling and blasting method.
  • Analyzed parameters derived from engineering experience and numerical simulations.
  • Conducted large-scale mechanized construction site tests and compared them with traditional approaches.
  • Investigated the influence of excavation methods and footage on surrounding rock characteristics.
  • Achieved a monthly footage of 110 meters, indicating a 10% increase in efficiency compared to traditional methods.
  • Reduced the number of tunnel face workers by 26.
  • Observed reductions of 18.6% in extrusion displacement and 4.5% in structural stress at the tunnel face.
