Abstract

We present validations and applications of the numerical Discontinuous Deformation Analysis method (DDA) for different cases of dynamic loading in the context of rock mass deformation. Following a review of 2D and 3D-DDA validations against analytical solutions for single and double face sliding, we present dynamic DDA applications in natural rock slopes and underground openings. Modelling dynamic rock slope deformation is demonstrated using the case of Masada rock slopes, with some new findings on the dynamic deformation of overhanging cliffs in general. Modelling underground deformation is demonstrated using the case of an active open pit mine in Israel developed in a rock mass containing multiple karstic caverns. The DDA method is shown here to be a powerful numerical tool for modelling dynamic rock mass deformation when the interaction between multiple discrete elements dictates the expected global deformation.
