Abstract
A model is proposed to explain the sliding of any glacier whose bottom surface is at the pressure melting point. Two mechanisms are considered. One is pressure melting and the other is creep rate enhancement through stress concentrations. Neither of the mechanisms operating alone is sufficient to explain sliding. If both mechanisms operate together appreciable sliding can occur. Résumé On propose un modèle pour expliquer le glissement d’un glacier dont le fond se maintient au point de fusion. On considère deux mécanismes: le fusion de pression et l’augmentation de la vitesse de déformation causée par les concentrations de tension. Ni l’un ni l’autre en agissant seul ne suffit à expliquer le glissement. Mais ensemble ils occasionneraient un glissement assez important.Keywords
