ƒ^ƒCƒgƒ‹�i‰p�j�F Three Dimensional Numerical Simulation for Rockfalls Application to a Rockfall due to the Western Tottori Earthquake 2000
�´˜^�i‰p�j�F Rockfalls axe of interest to engineers if they endanger human lives or structures. A numerical model using Distinct Element Method has been developed for the study of the spatial movement of blocks striking a three-dimensional topography. Uncertainties related to ground characteristics are treated with the Monte-Carlo Method, generating probabilistic values on their predefined distributions. This paper describes one application of this model to a rockfall which happened due to the western Tottori earthquake 2000. The result permits a delimitation of end -points (maximum reach) and possible trajectories. The topography of the rockfall slope is briefly described with other rockfall slopes.
