However, there is a lack of understanding on the interface behaviour between a rock bolt and bond material, especially on the crack initiation and propagation. The purpose of this paper is to investigate the effect of bolt configurations on the bolt-grout interface behaviour by discontinuous deformation analysis. By assessing the impact of key parameters, we can better understand the recommended parameter values and their impacts on the failure mechanism.||URI:||https://hdl.handle.net/10356/150738||ISSN:||0266-352X||DOI:||10.1016/j.compgeo.2018.09.017||Rights:||© 2018 Elsevier Ltd.
