MODELLING ROCK MASS IMPROVEMENT USING ROCK BOLTS
Keywords:Rock Bolts, Modelling, FEM
AbstractAnchor support currently represents a significant reinforcing technique in underground constructions. The principles of rock bolt reinforcement action are derived from various concepts of the underground excavation stability. In recent times, rock bolt design techniques have been complemented by numerical calculations procedures. The paper describes FEM modelling of a rock bolt system for mechanical and grouted bolts.
