translate English to French: Experiments were carried out during the 1967–1972 period in an attempt to measure cryostatic (frost-induced) pressures by means of soil pressure cells installed in nonsorted circles (mud hummocks) at Inuvik, N.W.T. Although slight soil pressure increases were measured in the hummocks during the freeze-back period, the field evidence shows that the hummock centers became desiccated, overconsolidated, and immobile rather than saturated, underconsolidated, and mobile, because of water loss to growing ice lenses at the top and bottom of the active layer.
Bien que de légers accroissements de pression aient été mesurés dans les tertres durant la période de regel, les observations de terrain montrent que les centres des cercles deviennent secs, indurés et immobiles plutôt que saturés en eau, ramollis et mobiles, à cause de la perte d'eau vers des lentilles de glace en voie d'accroissement au sommet et à la base de la couche active.
