Analyse, dimensionnement et optimisation d'ouvrages de protection contre les chutes de blocs
The Structurally Dissipating Rock-shed (SDR) is a new kind of protective structures. It uses directly the slab motion and the deformation of slab and fuse supports to dissipate impact energy of rock blocks. In this article, a simple and efficient numerical tool for SDR analyses is firstly presented. It has then been verified by the results of experimental tests. This tool has been applied to parametric design studies of SDR structures. Finally, different kinds of rock impact conditions have been studied with the help of this tool in order to optimize the SDR concept, particularly with respect to the punching shear. All theses studies show the robustness of the SDR concept, and permit to improve its design method.
