Le mouvement de terrain des Ruines de Séchilienne - localisé sur le versant Sud du Mont Sec (38) - fait l'objet depuis 1985, d'une étude approfondie des mouvements observés et potentiels, ainsi que d'une surveillance continue par le CETE de Lyon. Les mécanismes de déformation et rupture en profondeur de ce versant restent encore mal connus, du fait...

Field observations and movements measured since 1985 by the Lyon CETE (Public works regional engineering office) monitoring system at the Ruines de Séchilienne show that the slope deformation and fault mechanisms are complex. To provide a deeper understanding of these mechanisms, INERIS has been investigating the site through the instrumentation of...

The prevention of ground failures in mountainous areas - landslides and rock falls - rises severe issues as these geohazards are difficult to identify and quantify. A risk analysis is usually based on a geological and geotechnical study that includes the history of movements recorded in the area. When an identified phenomenon is impossible to stabi...

This paper describes a field experiment of stress measurement using the overcoring method performed in a rock slope, called Rochers de Valabres (located in France’s Southern Alps Region), a field laboratory site prone to rockfalls. Six measurements were conducted at shallow depths from the surface, moving deeper along a sub-horizontal borehole. The...

Risk management of natural ground failures or those of anthropogenic origin by means of operational monitoring requires the setting-up of performing early-warning systems. The goal is to sufficiently anticipate the natural catastrophe, unpredictable in time, and thereby guarantee acceptance of the risks by effective reduction in the vulnerability,...

Rockfalls and landslides are recognized as a major natural hazard across the Alps with strong economical and social impacts on regional land settlement and transportation policies. While numerous Alpine zones and valleys are prone to gravitational risks, climate change is becoming an important issue on whether or not the situation facing landslide...

The field experiment “VAL-STRESS3D”, started in 2005 by INERIS, aims to characterize and study both in situ stress and continuous thermomechanical deformations within the “Rochers de Valabres” rock slope, a Pilot Site Laboratory (PSL) prone to rockfalls. Firstly, in situ stress measurements were conducted along a profile rom the surface toward the...

The "Rochers de Valabres" is a fractured rock slope located in the French Alps and afected by rockfall. This slope has been chosen as an experimental site for improving knowledge on mechanisms leading to rockfall. Since 2002 scientific investigations (field observations, monitoring and numerical modelling) have been carried out on the site. A seism...

Although stress states in the ground are seldom well known with precision, such is especially true in slopes where the boundaries and initial conditions as well as topographic variations are difficult to grasp. As with other sites, it proves difficult to replicate the history of the tectonic stages the ground has undergone and the different rheolog...
