scope:

This document deals with field testing using Ménard pressermeter test as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2. The present document describes the procedure for conducting a Ménard pressuremeter test in natural soils, treated or untreated fills and in very hard soils, or soft rocks, either on land or off-shore. The Ménard pressuremeter test is performed by the radial expansion of a tricell probe placed in the ground (see Figure 1). During the injection of the liquid volume in the probe, the inflation of the three cells first brings the outer cover of the probe into contact with the borehole walls and then presses on them resulting in a soil displacement. Pressure applied to, and the associated volume expansion of the probe are measured and recorded so as to obtain the stress-strain relationship of the soil as tested. This Standard refers to a probe historically described as the 60 mm G type probe. This standard applies to test depths limited to 50 m and test pressure limited to 5 MPa.
