Experimental and numerical evaluation on debonding of fully grouted rockbolt under pull-out loading

International Journal of Coal Science & Technology, 2022
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.
