Prédisposition, préparation et déclenchement des mouvements de versant

Abstract

ABSTRACT Rock slope movements can be considered, from a mechanical standpoint, as the consequence of predisposition, preparation and trigger factors. In the case study of the “Rochers de Valabres” slope (Southern French Alps), which experienced major rockfalls in 2000 and 2004, these factors are analysed by means of field observations, high-precision geodetic monitoring and acoustic emissions monitoring, as well as by numerical modelling. This paper places special emphasis on the role of both the fracture network and thermal effects.
