The Geomechameter : A new in-situ geotechnical test

The Géomécamètre is a new in-situ test to measure all
mechanical characteristics needed for geotechnical and projets of
foundations. This device allows, through an external water circulation at the probe:
• To adjust the vertical stress at a level chosen by the experimenter
To measure the elastic modulus of the soil (Ee)
to measure the friction angle of the ground (Φ) and cohesion (c) of the soil
to measure the permeability coefficient (k) of the soil
To measure the coefficient of soil erosion (μ) and the critical gradient (icrit)
