O článku:
About 90 % of new landslides take place by activation of potential landslides due to man̉’s negative intervention in Slovakia. Antropogeneous interventions act on the stability of old, dormant landslides differently. The landslides are either artificialy loaded or undercut. Man’s activity induces changes in the regime of groundwaters or causes dynamic effects on the landslides. The paper analyses the cases of activization of old landslides due to the construction of civil or industrial structures, bridges, roads, tunnels, pipe-lines and water artificial reservoirs. Numerous landslides were induced by deforestation of land, incorrect agricultural melioration works, worsening of flow – off surface and underground waters and failures of the underground pipe-lines. The high number of artificially activated dormant landslides in the areas with an intense economic activity in Slovakia is alarming. With the constantly increasing urbanization of Slovakia, it can be expected that this trend will be maintained in the future, if we do not learn from the present mistakes. Man’s activity in the densely populated areas is becoming the most important geological factor. Its influence is activating landslides of bigger dimensions, which usually cause the biggest damage. However, the risk of renewing movements of old landslides may be reduced to the minimum, when we know the degree of danger, which threatens all the planned and existing structures in the sliding areas.
