ABSTRACT
The submitted paper presents partial results of the analysis of stability models of slopes typical of the flysch zone being frequently subject to gravitational deformations of the landslide type. Stability behaviour is assessed according to changes in basic parameters – input values for models of slope geological structures. It is a matter of the gradient of slope, saturation and changes in shear parameters of slopes formed by deluvial soils, hard rocks and a combination of both. To assess the impact of changes in the above-given values quantitatively, limit equilibrium methods and the comparison of them were used. The results unambiguously prove that the degree of stability is in all cases dependent especially on changes in the degree and character of slope saturation and, to a lesser extent, on changes in slope gradients. This model study can contribute to the more effective decision making on a suitable method of slope stabilisation in the Carpathian flysch zone potentially endangered by landslides.
