ESSAI PRESSIOMETRIQUE PDF

Les contraintes sont exerces sur les parois du cylindre, en contact avec le sol ou le roc en place, laide dun fluide agissant sous une ou des membranes dilatables. On obtient ainsi une relation effort-dformation qui peut-tre analyse thoriquement la diffrence des autre essais in-situ, ou empiriquement selon les hypothses sur les proprits du milieu. Figure 1 Hypothses lappareil exerce un champ de contraintes radiales uniformes sur une certaine longueur de la sonde. Cette hypothse a conduit la conception des sondes tricellulaires par Louis Mnard. Essais dans les roches les appareils utiliss sont appels dilatomtres. Dformations radiales dduites du volume inject ncessitant la mesure des dilatations parasites Tubulure dinjection coaxiale rduisant les dilatations parasites.
