Abstract
Real-scale impact experiments have been conducted on a rockfall protection embankment, over the 200–2,200 kJ kinetic energy range. The structure was made of a two-layer sandwich wall leaned against an earth-fill dam. Gabion cages either filled with stones or a sand-scrapped tire mixture constituted the sandwich wall. Different measuring devices were used to monitor the structure response: accelerometers, displacement sensors, high speed camera and geophysical survey. The structure and measuring devices are first described. The results presentation focuses on measurements within the structure for a low energy impact. Results concerning higher projectile kinetic energies are provided. The discussion highlights the main features of the embankment kinematic response based on displacements within the wall in particular.
