With recent developments in numerical codes, it is now possible to investigate the relation between kinematics and the damage required for the failure of rock slopes. This paper investigates the influence of kinematics and failure surface geometry on damage leading to the failure of rock slopes using a three-dimensional lattice spring code. Two new methods are introduced to quantify damage in the numerical simulations. In the first method, damage is quantified using “damage intensity” parameters, D21 and D32. In this method damage is defined as the ratio of total length/area of the newly created cracks within the model to the sampling area/volume. In the second method an “ellipsoid of damage” is defined to encompass newly created cracks within a given model. Geometrical characteristics of the ellipsoid including volume, length and orientation of its axes allow quantification of damage within the model. The numerical simulation results highlight the close connection between kinematics and damage in high rock slopes.
