INTERLOCK/FRICTION MODEL FOR DYNAMIC SHEAR RESPONSE IN NATURAL JOINTED ROCK

In this paper a system identification approach is used to formulate a discrete element analytical model to predict the behavior of natural jointed rock specimens subject to static normal stress and dynamic shear in a compliant loading apparatus. Model parameters are synthesized to correspond to various low and high frequency physical phenomena that are observed to occur in available experimental data for welded tuff specimens subject to harmonic shear. An approximate interlock/friction model is postulated for the rock interface dynamics, while various spring/mass and damper systems represent the loading apparatus.
