Cusp-Catastrophe-Based Evaluation of Critical Rockbolt–Grout Interface Debonding Displacement in Fully Grouted Rockbolts under Pull-Out Loading

ABSTRACT For a fully grouted rockbolt (FGR) subjected to pull-out loading, local instability may occur at the rockbolt–grout (R-G) interface when the surrounding medium is sufficiently stiff and the bolt–grout bond governs load transfer. This study derives a theoretical estimate...
