Definitions

  • the invention provides a reinforced impact absorption structure for distributing the energy of the impact laterally so as to allow the thickness of the structure to be reduced. If the use of reinforcements is known, they are typically arranged in the depth of an embankment, parallel to the direction in which it is expected to be loaded.
  • reinforcements are arranged so that their main directions of resistance are substantially parallel to each other and to the face (s) of the structure.
  • the main directions of resistance of the first reinforcements can be parallel to the first face of the backfill, and the same for the second face, where appropriate. It is nevertheless possible, in certain cases, for their orientation to deviate a little from the plane of the first face, or from the plane tangent to the latter if the first face is not plane.
  • the angle formed between these main directions and the first face must nevertheless remain an acute angle so that their projection on the first face is longer than their projection in the direction perpendicular to the first face, which gives good dissipation efficiency of energy in the event of impact in the perpendicular direction.
  • reinforcements extending from one another can therefore for example form a polygon matching the shape of the face.
  • a curved face will preferably have a large radius of curvature.
