Abstract

Une traverse en béton monobloc destinée à des rails de chemin de fer qui assure un rendement élevé en fonctionnement comporte une structure d'acier qui est formée de plaques d'acier haute résistance intrégrées dans un élément en béton et renfermant des câbles laminés à froid précontraints ayant des extrémités qui forment des nuds de tête de bouton qui sont ancrés aux plaques d'acier. Une géométrie à facettes permet un usage optimal du matériau et, ainsi, augmente linterconnexion traverse-ballast et la stabilité relativement à la surface de support.
