Modelización numérica de deslizamiento de Ceppo Morelli (Alpes Italianos)

Abstract

Great landslides are among the natural disasters that destroy the territory. During last October 2000, Ceppo Morelli, a little village in the Italian Alps, suffered heavy rainfalls that provoked the last landslide of the local history. These events affect negatively the course of everyday life. Modern society tries to apply the most advanced methods in order to prevent and mitigate such disasters. Our objective is to continue pioneer work on evaluation of the state of mountain slopes using the Finite Element Method (FEM) in order to detect risk of failure and apply appropriate corrective measures. Moreover, we are able to detect the origin of these instabilities, which we locate in the last deglatiation of the Quaternary Era. This process has been carried out in various steps. The first one consists in gathering and examining information to better understand the state of the site, and establish basic ideas that will be checked in situ. With these studies we are able to idealize the reality of the place and by removing side factors we obtain best results at minimum cost.
