“…2007;Ishida et al, 2004), underground powerhouses (Ishida et al, 1995), tunnels (Hirata et al, 2007) and nuclear fuel waste disposal (Major and McEvilly, 1985). Among these applications, AE monitoring of slope stability has recently advanced for not only rock cliffs (Amitrano et al, 2005;Senfaute et al, 2003;Ishida et al, 2001) but also mudslides (Amitrano et al 2007) by using active and passive waveguides, helping to overcome many of the difficulties associated with such monitoring (Dixon et al, 1996(Dixon et al, , 2003a(Dixon et al, , 2003b. However, AE occurrence itself strongly depends on geological conditions (Milev and Spottiswoode, 2002), as well as mining configurations (Senfaute et al, 1997(Senfaute et al, , 2001.…”

“…Afin de détecter ces mouvements, différents procédés d'auscultation et de surveillance par écoute micro-sismique ont déjà fait leurs preuves dans plusieurs domaines, tels que l'exploitation de mines de charbon profondes, la géothermie et l'extraction des hydrocarbures. L'application aux versants rocheux potentiellement instables est plus récente, mais montre déjà des résultats prometteurs (Senfaute et al, 2003 ;Ishida et al, 2001).…”

Afin de mieux comprendre les mécanismes sous-jacents aux mouvements des versants rocheux, nous proposons d'en analyser les causes possibles en distinguant les facteurs de prédisposition, les facteurs préparatoires et les facteurs déclencheurs. Nous montrons ici que la fracturation initiale du massif rocheux constitue un facteur de prédisposition aux instabilités et que les fluctuations thermiques de surface peuvent en constituer un facteur préparatoire. Cette approche s'appuie sur l'exemple du versant des Rochers de Valabres (Alpes-Maritimes), qui a été le siège d'importants éboulements en mai 2000 et en octobre 2004 et sur lequel des investigations sont réalisées par le biais, notamment, de la modélisation numérique et d'une instrumentation in situ.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. MOTS-CLÉS : versant rocheux, éboulement, auscultation, modélisation numérique, thermomécanique.
