适用范围

This document comprises requirements for investigations of soil and weak rock by pressuremeter tests with the self-boring pressuremeter (SBP) as part of the geotechnical investigation services according to EN 1997-1 and EN 1997-2.Tests with the self-boring pressuremeter cover the measurement in situ of the deformation of soils and weak rocks by the expansion and contraction of a cylindrical flexible membrane under pressure.The SBP is drilled into the ground using an integral self-boring head at its lower end in such a way that the probe replaces the material it removes so creating its own test hole and minimises the disturbance to the soil outside the instrument.Pressure applied to, and the associated expansion of the probe are measured and recorded so as to obtain the stress-displacement relationship for the soil as tested.During both boring and testing the data is recorded automatically.
