Abstract
Numerical modelling of fully grouted rock bolts loaded in tension is presented by implementing a non-linear bond-slip relationship of bolt-grout interface into a commercial finite difference rock mechanics code. The proposed model shows a close match with the experimental results and analytical predictions in terms of load-displacement relationship, rock bolt axial force distribution and interfacial shear stress distribution. A detailed debonding failure process is also presented, which includes five successive states: elastic state, elastic-softening state, elastic-softening-debonding state, softening-debonding state and debonding state.
