ABSTRACT
Cable bolts have been identified as a very economic and rapid ground control system in different mining and civil engineering projects. For an effective support system, understanding the performance of cable bolts under the conditions other than those conducted in the laboratory is essential. This study aims to develop an analytical model that can predict the load-displacement performance of the modified cable bolts at different confinements. The load-displacement behaviour of modified cable bolts with a smooth transition from initial elastic behaviour to progressive failure is simulated based on continuous yielding method. The model is then calibrated against the experimental data reported in the literature. It has been shown that there is a good agreement between the model simulations and the experimental results approving the suitability of the introduced model for performance prediction of the modified cable bolts at different confining pressures.
