Fully-grouted rock bolts are widely used in mining and geotechnical engineering to improve rock mass stability and thus ensure safety. The interfacial and axial response of a bolting system to a tensile load is very complex and is associated with rock bolts mechanical properties, mechanical characteristics of grout, geo-mechanical properties of rock mass and boundary conditions. Although a large number of studies have been carried out to evaluate and characterise the performance of fully-grouted rock bolts, an investigation is still required to comprehensively characterise the influential factors affecting the axial load transfer mechanism of rock bolts. This study aims to systematically study the combined effects of these factors by conducting a series of experimental investigations and developing numerical models.
