Numerical modelling of the landslide processes using discontinuous approach

Principles and examples of discontinuous numerical modelling of the landslide slopes are presented in the paper. In many cases, rock mass is composed of relatively strong and com petent rock blocks, which are intersected with discontinuities, such as joints, faults, fault zones, bedding planes, etc. Deformation process of such system is modelled numerically, using UDEC (Universal Distinct Element Code) computer programme. This approach is explained in the paper, and two examples of numerical simulation of the landslide development illustrate its main features. The first example is concerned with the landslide modelling in a diabase quarry, whereas the second one presents the simulation of the process in the Italian Dolomites. The results prove the appropriateness and usefulness of the discontinuous modelling approach.
