COMPORTEMENT D'OUVRAGES DE PROTECTION EN BÉTON ARMÉ SOUS IMPACTS SÉVÈRES ANALYSES ET PROPOSITIONS

Abstract : This document considers the consequences of rock falls on protective structures and especially their effects on the design and the monitoring of such structures. The first part is devoted to innovative multilayer structures for building's protection against rock falls with energies below the megajoule. The second part is devoted to rock-sheds like SDR (Structurally Dissipating Rock-shed) with an horizontal slab built to protect roads, railways, against rock falls impacts up to 20 MJ. The first studies have been completed here by the study of the behavior of DSP built with a sloped slab. The last part concerns the monitoring of DSP: as it has been discussed in the second part, the DSP may be damaged by exceptional impacts and it seems important to do a follow-up of these works by characterizing the impact location and the load level. For this, we used an approach based on inverse analysis and first results are presented. Finally this paper concludes with a discussion of the different approaches and ways which are to be explored.
