Abstract

Diskontinuiteti i njegove karakteristike imaju najvažniju ulogu u mogućnosti pojave sloma te njihov nagib i smjer nagiba mogu formirati različite vrste slomova. Neki od tih vrsta slomova su ravni, klinasti, rotacijski i slom prevrtanjem. U ovom diplomskom prikazana je problematika klinastog sloma za čije formiranje su potrebne dvije ravnine sloma koje se sijeku. Razlikujemo dva pristupa proračuna stabilnosti kosina, deterministički i probabilistički. Deterministički pristup kao rezultat daje faktor sigurnosti koji mora biti veći ili jednak jedan kako bi neku kosinu proglasili stabilnom, a parametri u proračunu su jednoznačno određeni, dok to nije slučaj za probabilistički pristup. Vjerojatnost pojave sloma uz parametre koji variraju za određenu standardnu devijaciju, te uz postavljeni relativni minimum, maksimum i srednju vrijednosti rezultat je probabilističkog pristupa. Na kraju rada pomoću programa SWedge iz programskog paketa Rocseince prikazati će pet različitih slučajeva utjecaja prisutnosti kohezije, vanjskog opterećenja, vode i potresa na stabilnost kosine koristeći probabilističku analizu.

Abstract (english)

Discontinuities and their characteristics play the most important role in the possibility of failure, and their inclination and direction of inclination can form different types of failures. Some of these types of failure are plane, wedge, rotational and rollover failure. This thesis presents the issue of wedge failure, the formation of which requires two intersecting failure planes. We distinguish between two approaches to calculating slope stability, deterministic and probabilistic. As a result, the deterministic approach gives a safety factor that must be greater than or equal to one in order to declare a slope stable, and the parameters in the calculation are unambiguously determined, while this is not the case for the probabilistic approach. The probability of failure with parameters that vary by a certain standard deviation, and with set relative minimum, maximum and mean values is the result of a probabilistic approach. At the end of the work, using the SWedge program from the Rocseince software package, five different cases of the influence of the presence of cohesion, external load, water and earthquakes on slope stability will be presented using probabilistic analysis.
