Abstract
The device comprises a corer (1, 4) fitted with a flexible diaphragm (2) on its inside face, means (10) for driving the corer into the soil (11), means for breaking up the soil leaving the top orifice of the corer, means for applying axial forces on the diaphragm (2) and on the top face of the soil sample (12) contained in the corer, and means for measuring stresses and deformations to which the sample (12) is subject. While a measurement is being performed, the corer is held stationary in the soil (11).
