A Discontinuous Approach to the Numerical Modelling of Rock Avalanches
Summary. The runout of dry rock avalanches produced by planar rockslides affecting a limestone formation with clayey interbeds is analysed by means of distinct element modelling. Potential and past rock avalanche events are described with reference to the geotechnical and structural conditions of the slope, typical of several Alpine valleys. Runout prediction analyses of potential rock avalanches performed with the $ PFC^{2D} $ code are based on independent measurement of strength, energy dissipation and stiffness parameters of the rock mass and are validated by means of the back analysis of a historical rockslide occurred in the investigated area. Physical aspects of the avalanching process evidenced by modelling are also discussed.
