Experimental and numerical evaluation on debonding of fully grouted rockbolt under pull-out loading
Abstract The axial loading in rockbolts changes due to stress redistribution and rheology in the country rock mass. Such a change may lead to debonding at rockbolt to grout interface or rupture of the rockbolt. In this study, based on laboratory experiments, ultrasonic guided wave propagation in ful...
