Summary

Near the town Handlová, the geologic-geomorphological development resulted in a typical slope deformation structure. Hard and rigid volcanic rocks rest upon plastic Palaeogene and Neogene clayey rocks. The block type deformations like block rifts, block fields and areal landslides are predominant, flow slides are less frequent. Block deformations are controlled by tectonics (association with elevation structures). Landslides are mostly controlled by physical-mechanical properties of clayey rock. They are favoured by hydrogeological conditions and by climatic factors. Some landslides are activated by undermining of slopes. Protective operations mostly comprise drainage, anchors, piles, and stabilizing embankments.

Résumé

Une structure typique de déformation de pente s'est formée aux alentours de Handlová. Les roches volcaniques dures et cassantes, de la montagne de Vtáčník et Kremnické hory y reposent sur les assises meubles du Paléogene ou du Néogène. Parmi les déformations prédominent celles du type à blocs, les entailles en blocs, les champs de blocs, les glissements de terrain superficiels; les coulées sont moins fréquentes. C'est la structure tectonique qui conditionne la genèse des déformations en blocs. Les glissements sont influencés surtout par les propriétés physico-mécaniques des roches argileuses. Les conditions hydrogéologiques et climatiques contribuent aussi d'une manière importante à la naissance des glissements. Une partie de ceux-ci est mise en marche sous l'effet de l'extraction souterraine. Parmi les travaux confortatifs, sont surtout efficaces les différentes méthodes de drainage, les tirants, les pieux et les digues de stabilisation.
