New Cadanav methodology for quantitative rock fall hazard assessment and zoning at the local scale

Vincent Labiouse, Jacopo Maria Abbruzzese

Rock fall hazard zoning is a challenging yet necessary task to be accomplished for planning an appropriate land use in mountainous areas. Methodologies currently adopted for elaborating zoning maps do not provide satisfactory results though, due to uncerta ...

Hollow cylinder simulation experiments of galleries in Boom Clay formation

Vincent Labiouse, Claire Sauthier, Shuang You

In the context of nuclear waste disposal in clay formations, laboratory experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) induced by the construction of galleries in the Boom Clay formation. For this purpose, thick-wall ...

Empirical and analytical analyses of laboratory granular flows to investigate rock avalanche propagation

Vincent Labiouse, Irene Manzella

Laboratory experiments which consist of releasing dry rigid non-cohesive grains or small bricks on an unconfined chute have been designed to investigate rock avalanche propagation mechanisms and to identify parameters influencing their deposit characterist ...

Laboratory and in Situ Simulation Tests of the Fracturing in the EDZ around Galleries in Opalinus Clay

Vincent Labiouse

Within the framework of the TIMODAZ project laboratory and in-situ experiments have been performed to study the failure processes around tunnels in laminated clay rich sedimentary rocks at reduced scale. The fracture patterns observed in the hollow cylinde ...

Thermo-Hydro-Mechanical Modelling of Hollow Cylinder Laboratory Experiments on Boom Clay

Vincent Labiouse, Bertrand François

The aim of the TIMODAZ project is to investigate the effect of thermal changes on the excavation damaged zone (EDZ) around nuclear deep disposals in clay-based geological formations. In the framework of WP5.2 of this project, it is intended to develop cons ...

Self-Sealing of Localised Cracks in Boom and Opalinus Clay Hollow Cylinders

Laurent Gastaldo, Vincent Labiouse, Jean-François Mathier

The SELFRAC project aimed to study the fractures within the Excavation Damaged Zone (EDZ) around galleries in the Boom clay and Opalinus clay formations and their possible sealing/healing with time. Tests carried out at LMR-EPFL aimed at quantifying on the ...

Identification and analysis of Swiss National Road tunnels pathologies

Federica Sandrone, Vincent Labiouse

In order to evaluate the general conditions (i.e. safety, serviceability and durability) of tunnels, a detailed analysis of the lining structure and surrounding rock mass is required. During the service life of the tunnel, regular survey activities should ...

An X-ray computed tomography-based index to characterize the quality of cataclastic carbonate rock samples

Aurèle Parriaux, Pascal Turberg, Vincent Labiouse, Reto Meuli, Pierre Guillaume Christe

X-ray computed tomography (XRCT) can reconstruct, in a nondestructive way and in three-dimension, the distribution of densities within opaque materials. Consequently, it provides an effective possibility to characterize the inner content of rock core sampl ...

Technical note: Preliminary estimation of rockfall runout zones

Vincent Labiouse

Rockfall propagation areas can be determined using a simple geometric rule known as shadow angle or energy line method based on a simple Coulomb frictional model implemented in the CONEFALL computer program. Runout zones are estimated from a digital terrai ...
