Abstract

Srž proračuna su profili 6 i 8 jalovišta Istočni greben koji pripada kompleksu kamenoloma Očura u Lepoglavi. Na profilima je provedena povratna analiza pomoću računalnog programa Slope Stability, kako bi se za zadane vrijednosti provjerilo ponašanje kliznih ploha. Svaki se profil analizirao za šest različitih vrijednosti kohezija (0,1 kPa; 1,0 kPa; 2,0 kPa; 3,0 kPa; 4,0 kPa i 5,0 kPa). Unutar jedne od šest varijanti je kohezija bila konstantna, dok se kut unutarnjeg trenja uvijek mijenjao za iste iznose (26°, 28°, 30°, 32°, 33°, 34°, 36° i 38°). Numerički je proračun baziran na Bishopovoj metodi opće granične ravnoteže koja automatski pronalazi optimiziranu kliznu plohu. Analiza rezultata je pokazala da se volumen klizne plohe povećava s rastom kohezije.

Abstract (english)

The bases of the calculation are the profiles 6 and 8 of Istočni greben, which belongs to the Očura quarry complex in Lepoglava. The profiles were back analyzed using the Slope Stability program in order to verify the behavior of the sliding surfaces for the default values. Each profile has been analyzed for six different values of cohesion (0.1 kPa, 1.0 kPa, 2.0 kPa, 3.0 kPa, 4.0 kPa and 5.0 kPa). Within one of the six variants, the cohesion has been constant, while the inner friction angle always changed by the same amounts (26 °, 28 °, 30 °, 32 °, 33 °, 34 °, 36 ° and 38 °). The numerical calculation is based on Bishop's general limit equilibrium method that automatically finds an optimized sliding plane. Analysis of the results has shown that the volume of the sliding surface increases with the growth of cohesion.
