This thesis presents an analysis of the stabilisation of a small translational landslide on a terraced vineyard slope near Velike Žablje in the Municipality of Ajdovščina. The aim was to compare the effectiveness of three stabilisation measures — a concrete-bound stone retaining structure, micropiles, and benching of the slip surface — in terms of improving the global stability of the slope. The landslide geometry was determined based on field measurements, an unmanned aerial vehicle survey, and elevation profiles. The soil was classified according to the USCS, and shear parameters were estimated using direct shear tests. The global stability of the analysed variants was assessed using Rocscience Slide2 with the GLE/Morgenstern–Price method. The initial condition had a factor of safety of Fs = 1.008. The analyses showed that the concrete-bound stone retaining structure satisfied the local stability checks, but the global factor of safety remained 1.120. A single row of micropiles did not achieve the required factor of safety Fs ≥ 1.15, while two and three appropriately positioned rows achieved Fs = 1.202–1.204 and Fs = 1.332–1.334, respectively. Both benching variants met the required safety criterion, with Fs = 1.181 and Fs = 1.269. Although the two- and three-row micropile variants also met the safety criterion, benching was selected as the most suitable solution due to its simpler on-site implementation. The results provide a basis for selecting an appropriate stabilisation measure; further optimisation of the benching geometry and additional geotechnical and design verifications are required for the detailed design project.
