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 ...

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

Federica Sandrone, Vincent Labiouse

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 ...

Improved analytical solutions for the response of underground excavations in rock masses satisfying the generalized Hoek-Brown failure criterion

Vincent Labiouse

Analytical solutions for tunnel design are widely used in practical engineering, as they allow a quick analysis of design issues such as estimation of support requirement. In recent years, several papers analyzing the behavior of rock masses that obey the ...

Quantitative analysis of deformation in hollow cylinder tests on anisotropic clay formations

Vincent Labiouse, Gioacchino Viggiani, Shuang You

A series of triaxial laboratory experiments are performed on thick-walled hollow cylindrical samples of boom clay. The aim of this testing program is to better understand the anisotropic deformation during the excavation. The testing conditions are similar ...

New Developments in Rock Fall Hazard Assessment and Zoning: An Application of the Cadanav Methodology

Vincent Labiouse, Jacopo Maria Abbruzzese

Rock fall hazard assessment and zoning are very important for an appropriate land use planning in mountainous areas. However, they are complex topics, and current methodologies adopted for producing zoning maps do not provide satisfactory results, due to a ...

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 ...

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 ...

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. ...

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 ...

Consequences of the Thermal Transient on the Evolution of the Damaged Zone Around a Repository for Heat-Emitting High-Level Radioactive Waste in a Clay Formation: a Performance Assessment Perspective

Vincent Labiouse, Xing Li, Li Yu

A proper evaluation of the perturbations of the host rock induced by the excavation and the emplacement of exothermic wastes is essential for the assessment of the long-term safety of high-level radioactive waste disposals in clay formations. The impact of ...
