In-situ validation of an innovative mono-cell pressuremeter probe: first results

The present paper focuses on the first in-situ Mono-cell FC probe tests performed in sands and clays, and the evaluation of soil’s deformability properties at low strain level.

Membranes for pressuremeter probes have been considerably improved through recent technological innovation. The Mono-cell FC® probe takes advantage of these evolutions with a potential measuring range from small strain to complete soil failure. An experimental program was established to validate its measuring capabilities through both laboratory and in-situ tests. The present paper focuses on the description of the laboratory testing protocols, leading to the evaluation of soil’s deformability properties at low strain level whilst using this probe. The obtained results were compared with those derived from laboratory tests in the same soil type as described in literature. A discussion is held regarding the first results and the required stress and strain level adjustment for the case of dry sands.
