Theme 2 Deep-Reaching Gravitational Deformations of Mountain Slopes Relationship Between Tectonic and Gravitational Deformations Technical-Economic Importance of These Deformations for Engineering Structures Communications

Summary

Deep-seated creep deformations of slopes attaining kilometres in dimensions occur quite often even in the metamorphosed rocks and granitoids forming the crystalline core of the Tatry and Nízke Tatry Mts. They have a form of gravitational folding and fan-like disintegration of mountain slopes. In both cases, however, a similar model of failure mechanism can be assumed on the basis of contractant-dilation behaviour of rock masses. To this model of deformation correspond well the geomorphological manifestations of 138 deformations we detected. These slope deformations can cause serious economic losses.

Profondes déformations de fluage dans le noyau cristallin des tatras

Résumé

De profondes déformations de fluage des versants atteignant des kilomètres se produisent assez souvent même dans les roches métamorphosées et les granitoïdes formant le noyau cristallin des Mts. de Tatry et Nízke Tatry. Elles ont une forme de plissement de gravité et de déformation en éventail des versants de montagnes. Dans les deux cas, cependant, on peut supposer sur la base du comportement contractant-dilatant des massifs rocheux un modèle similaire du mécanisme de la désagrégation. A ce modèle de la désagrégation correspondent bien les manifestations géomorphologiques des 138 deformations trouvées. Ces déformations des versants peuvent causer de pertes sérieuses.
