Summary

Peculiarities and change of stress state in isotropic, anisotropic and non-uniform masses at the foot and base of rock slopes when creating deep reservoirs are considered. Data on permanent observations of slope stresses before and at the time of filling the reservoir are given. The analysis shows the influence of filling on the rate of movement along slope fractures.

Résumé

L'article analyse les particularités de l'état de tension et de déformation de massifs isotropes, anisotropes et hétérogènes au pied et à la base de pentes rocheuses et sa modification à la création de réservoirs profonds. On donne les résultats des observations de longues durées des modifications des pentes avant et après remplissage des réservoirs; l'analyse montre l'influence essentielle du remplissage des réservoirs sur la vitesse du mouvement le long des fractures des pentes.
