10 years of thermo-mechanical monitoring of rock columns - les chandelles de l'Escalette, France

10 ans de suivi thermomécanique des colonnes rocheuses - les chandelles de l’EscaletteFrance

Abstract

Rock instabilities can represent major risks for local populations depending on their geographical location. Even if different factors such as precipitation, seismic activity and freezing, are known to trigger rockfalls it is more and more assumed that thermal cycling have a role in cracking initiation or propagation. Here we use data of the first six years of field monitoring of a 50meter-high French dolomitic cliff, located above an important highway in the south of France (A75) to support this thinking. Evolution of the aperture of joints and temperature were followed on ten different locations around les Chandelles de l'Escalette. Results will be discussed in terms of mechanical response to temperature variations.
