A new molecular dynamics-like modelling approach aimed at simulating the mechanical behaviour of true polyhedra dense assemblies is presented. Thanks to an improved version of the Gilbert-Johnson-Keerthi contact detection algorithm called GJK - TD, this approach involves no edge or corner rounding and accounts for multipoint face - face or edge - f...
The conventional crumb test (CCT) is a simple and rapid test, originally used for assessing the dispersive tendency of clayey soils through visual observation of a small-scale soil specimen placed in a large volume of water. In this study, the disaggregation process occurring in soil in contact with water was followed in place of the soil dispersio...

In mountainous areas, unreinforced concrete wall is a commonly used building way for new constructions. Actually this technique offers a suitable strength in case of construction in a slope. In these areas prone to rockfall hazard, the vulnerability of constructions to this hazard has to be considered. Even if numerous studies on the impact strengt...
Constructions located in mountainous areas are highly prone to rockfall impact risks. ln order to ensure people's safety, a robust design is necessary, then the understanding of concrete wall damages and failures caused by dynamic phenomena are highly needed. However, the scientific literature barely studied the behavior of concrete slabs, whereas ...
Concilier paysage et technique n'est pas chose impossible. Le présent guide technique propose une méthode permettant l'intégration paysagère des dispositifs de protection contre les chutes de blocs. Il précise les adaptations à mettre en oeuvre dans le cas de sites protégés ou à fort caractère patrimonial, pour lesquels les parades rocheuses peuven...
