Overview

Uniaxial compression tests revealed bolting improves strength and alters failure mode in jointed rock with varying roughness coefficients, suggesting design implications for stabilization.

Key Points

  • Increased joint roughness resulted in significant changes in the failure mode of jointed rock specimens, highlighting the dynamic response of rock materials.
  • The study utilized uniaxial compression tests with acoustic emission and digital image correlation systems to analyze specimen behavior effectively.
  • As joint roughness coefficients increased, the performance gains from bolting diminished, indicating a critical threshold for effectiveness.
  • Investigation reflects the complex interplay between structural reinforcement and natural material properties, emphasizing engineering considerations in rock stabilization.
