DANSK DSF/FPREN ISO 22476-8 PDF

This document comprises requirements for investigations of soil and weak rock by pressuremeter tests with the full displacement pressuremeter (FDP) as part of the geotechnical investigation services according to EN 1997-1 and EN 1997-2. Tests with the full displacement pressuremeter cover the measurement in situ of the deformation of soils and weak rocks by the expansion/contraction of a cylindrical flexible membrane under pressure. The FDP is jacked into the ground with an integral cone at its lower end thereby creating its own test hole. FDP equipment may take a number of forms therefore descriptions are given in accordance with the type of installation and measuring systems
