Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

Deep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

Deep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...
