Borehole jack test 99 experimental

The borehole jack test consists in the installation of two diametral cylindrical steel loading plates in the ground and opened by pressure. Pressure applied to, and associated opening of the probe are measured and recorded so as to obtain a stress-displacement relationship of the ground for the range of the expected design stress. The tes is applicable in ground stiff enough not to be adversely affected by the drilling operation

fr L'essai au dilatomètre rigide diamétral consiste à placer deux coquilles de chargement en acier cylindriques et diamétrales dans le terrain et déplacées par pression. La pression appliquée et le déplacement associé sont mesurés et enregistrés de manière à déterminer la relation contrainte-déplacement du terrain dans la plage des contraintes estimées dans le cadre de l’étude. L'essai est applicable dans un terrain suffisamment ferme pour ne pas être affecté par l'opération de forage.
