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)
