ABSTRACT: Axial load behaviour of rock bolts was studied using FLAC commercial software in a two-dimensional framework. The numerical model was calibrated using experimental pull out data. Effects of confinement stresses and rock bolt surface roughness on the axial load behaviour were investigated incorporating the calibrated numerical code. Results indicated that the pull out resistance increases with an increase in confinement stresses and surface roughness.
