New Cadanav Methodology for Rock Fall Hazard Zoning Based on 3D Trajectory Modelling

Vincent Labiouse, Jacopo Maria Abbruzzese

Most rock fall hazard zoning methodologies are currently based on trajectory modelling, usually performed along 2D slope profiles. For many topographic configurations, this approach cannot provide a realistic description of the way rock fall trajectories a ...

Hollow cylinder simulation experiments of galleries in Boom Clay formation

Shuang You, Vincent Labiouse, Claire Sauthier

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 ...

Hollow Cylinder Tests on Boom Clay: Modelling of Strain Localization in the Anisotropic Excavation Damaged Zone

Vincent Labiouse, Bertrand François

Boom Clay is extensively studied as a potential candidate to host underground nuclear waste disposal in Belgium. To guarantee the safety of such a disposal, the mechanical behaviour of the clay during gallery excavation must be properly predicted. In that ...

A GIS based approach for analysing geological and operation conditions influence on road tunnels degradation

Vincent Labiouse, Federica Sandrone

Adopting effective maintenance strategies for transportation infrastructures requires good prediction of their long-term behaviour. For planning interventions without affecting the entire network’s capacity, tunnels in particular require a good overview of ...

Flow experiments with gravel and blocks at small scale to investigate parameters and mechanisms involved in rock avalanches

Vincent Labiouse, Irene Manzella

Laboratory experiments play an important role in improving the modelling of rock avalanches since they contribute to a better understanding of the mechanisms that characterise propagation and to identifying parameters influencing velocity and deposit chara ...

Laboratory and in situ simulation tests of the Excavation Damaged Zone around galleries in Opalinus Clay

Vincent Labiouse

In the context of nuclear waste disposal in clay formations, laboratory and in situ simulation experiments were performed to study at reduced scale the Excavation Damaged Zone (EDZ) around tunnels in the indurated Opalinus Clay at Mont Terri, Switzerland. ...

Brittle rock failure in the Steg lateral adit of the Lötschberg base tunnel

Vincent Labiouse

During the crossing of brittle rock formations at the Lötschberg base tunnel, failure phenomena have been observed both at the tunnel face and at the walls. A detailed analysis has been undertaken to explain these behaviours, based on the recent developmen ...

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 ...

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 ...

Considerations on Swiss methodologies for rock fall hazard mapping based on trajectory modelling

Vincent Labiouse, Jacopo Maria Abbruzzese, Claire Sauthier

Rock fall hazard assessment and hazard mapping are essential for the risk management of vulnerable areas. This paper analyses some issues concerning fragmental rock fall hazard mapping methodologies. Two Swiss approaches based on rock fall trajectory simul ...

Numerical modelling of gravel unconstrained flow experiments with the DAN(3D) and RASH(3D) codes

Vincent Labiouse, Claire Sauthier

Landslide continuum dynamic models have improved considerably in the last years, but a consensus on the best method of calibrating the input resistance parameter values for predictive analyses has not yet emerged. In the present paper, numerical simulation ...

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 ...

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 ...

Comparison of two rock fall hazard mapping methodologies based on the French and Swiss guidelines

Vincent Labiouse, Jacopo Maria Abbruzzese

Landslide hazard mapping aims at providing very useful information for urban planning and for risk analysis. Though landslide risks represent a common threat to human lives and properties worldwide, the procedures applied for hazard and risk assessment are ...

Challenges in achieving European-wide methodologies for rock fall hazard mapping

Vincent Labiouse, Jacopo Maria Abbruzzese

European-wide standard methodologies for rock fall hazard assessment and mapping would constitute a very important step towards more transparent and reproducible procedures used for these purposes, and would provide as well a higher uniformity in land use ...

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

Vincent Labiouse, Jean-François Mathier, Laurent Gastaldo

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 ...

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 ...

Ageing of chalk rocks in underground quarries

Vincent Labiouse

In the present work, an attempt has been achieved to describe the effects of ageing and of water on the hydro-mechanical behaviour of chalks from underground quarries of northern Parisian basin. Physical and mechanical properties were obtained as a functio ...

Identification and analysis of Swiss National Road tunnels pathologies

Vincent Labiouse, Federica Sandrone

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 ...
