The Ménard pressuremeter (Control Unit), plastic tubing and 3-cell probe allows to perform in situ Pressuremeter
test in soils according to the ISO 22476-4 and ASTM D4719-07 standards.
From the test readings (volume variation based on controlled pressure), a stress-strain curve can be obtained, in the case of plane deformation, which yields:
the Ménard Pressuremeter modulus (EM),
the creep pressure (Pf),
the Ménard limit pressure (Pl).
The borehole is drilled so as to minimize wall disturbance and to keep a cavity diameter compatible with the probe size (63 mm or 76 mm).
As soon as the probe is lowered into the borehole to the required test depth, the operator can start the test execution by pressure increments with the control unit
Applications
In situ stress controlled loading test performed on the wall of a borehole using a cylindrical probe which can expand radially.
Data acquisition system
GeoSPAD® allows the acquisition of pressumeter data via the central unit for soil investigation GeoBOX®. This system displays the conduct of pressuremeter tests and automatically records the conditions and results of these tests. |
