Abstract

Pour contrôler la mise en tension d’un câble de structure (12) par un vérin hydraulique (14) ayant une chambre de tension et des blocs d’ancrage du câble, le dispositif de contrôle (10) comprend un circuit d’alimentation (16) du vérin hydraulique (14), un compteur volumétrique (22) monté sur le circuit d’alimentation (16), un capteur de pression (24) monté sur le circuit d’alimentation (16), et un calculateur (26) relié au compteur volumétrique (22) et au capteur de pression (24) pour estimer l’allongement du câble de structure (12) et l’effort de traction régnant dans celui-ci.
