Rockfall characterization and structural protection - a review

Vincent Labiouse, Michel Jaboyedoff

Rockfall is an extremely rapid process involving long travel distances. Due to these features, when an event occurs, the ability to take evasive action is practically zero and, thus, the risk of injury or loss of life is high. Damage to buildings and infra ...

Methods for predicting rockfall trajectories and runout zones

Vincent Labiouse

Rockfall hazard assessment without the use of rockfall trajectory and runout zone models is unthinkable in the 21st century. Such rockfall models have existed since the sixties, but nowadays an almost confusing palette of rockfall trajectory and runout zon ...

Coupled Hydrogeological and Geomechanical Modelling for the Analysis of Slowly-Moving Landslides

Lyesse Laloui, Alessio Ferrari

Slow movements of natural slopes are quite frequent in mountainous or hilly areas. They may display occasional crises, mostly related to the increase of pore water pressures induced by exceptional climatic conditions. A methodology consisting of combining ...

Mechanics of Unsaturated Geomaterials

Lyesse Laloui

An understanding of the mechanics of unsaturated geomaterials has become an important component of the background of a geo-engineer operating in various fields of geomechanics. Several geotechnical operations, such as compaction and excavation processes, a ...

Geological characterization of cataclastic rock samples using medical X-ray computerized tomography

Pierre Guillaume Christe

Technical difficulties associated with tunnelling operations in tectonized geological settings are frequently encountered. They may include instantaneous and delayed cavity convergence, sudden collapse of walls or roof of a gallery, outpouring of fault-fil ...

Enhanced viscoplastic modelling of soft soils

Lyesse Laloui

Geotechnical experimental observations of the influence of strain rate on the mechanical behaviour of soft soils express fundamental microscopic processes. The main macroscopical displays are creep, relaxation and strain-rate effect on strength. With these ...

Numerics for geotechnics and structures. Recent developments in ZSoil.PC

Civil engineers are more and more often confronted with constructions in urban environment. It is then essential to be able to accurately assess the initial state, and the evolution of the safety during construction stages. While traditional geotechnical e ...

Shear stress mapping on the Lauter river

John Beck

In the framework of the INTERREG IIIb NWE project « Strategies and Actions for Flood Risk Management » (SAFER), a regional streambank erosion hazard model has been developed. This diagnostic model is tested on the Lauter River in Germany. Shear stress maps ...

Correlations between adhesion hysteresis and friction at molecular scales

Andrzej Kulik, Gérard Gremaud

Correlations between adhesion hysteresis and local friction are theoretically and experimentally investigated. The model is based on the classical theory of adhesional friction, contact mechanics, capillary hysteresis, and nanoscale roughness. Adhesion hys ...
