Influence of internal friction angle on slope stability in incoherent soil : master's thesis

Kosine su sastavan dio rudarske i geotehničke struke. U svrhu analize sigurnosti istih tokom godina su osmišljene mnoge metode proračuna. Metode se jedna od druge razlikuju u mogućnosti primjene i složenosti. Jasno je da će rezultati proračuna prvenstveno ovisiti o ulaznim podacima. Jedan od najvažnijih ulaznih podataka proračuna stabilnosti je kut unutarnjeg trenja. Iako postoji mnogo metoda za procjenu kuta unutarnjeg trenja niti jedna od njih nije posve prilagođena za ispitivanje šljunaka. Kako se u posljednjih par desetljeća šljunak sve više koristi u geotehničkim radovima sve više je potrebnije saznanje o ponašanju ovog materijala. U ovom radu će se kroz analizu stabilnosti kosine koristeći program PLAXIS 2D ustvrditi povezanost kuta unutarnjeg trenja šljunka s faktorom sigurnosti.Slopes are an integral part of the mining and geotechnical profession. To analyze their safety, many calculation methods have been devised over the years. These calculation methods differ one from the other in their applicability and complexity. The results of such a calculation will primarily depend on the input data. One of the most important input datums in a stability calculation is the internal friction angle. Although there are many methods of estimating the internal friction angle, none of them is completely adapted to gravel. As gravel has been used increasingly in geotechnical works in the last few decades, it is becoming necessary to learn about its behaviour. In this paper, the stability of slopes will be analyzed using the PLAXIS 2D program to determine the relationship between the internal friction angle of gravel and the safety factor
