Abstract

Stabilnost kosina predstavlja jedan od većih izazova u rudarstvu i geotehnici. Razvojem
znanosti i računala razvijene su i brojne metode i načini proračuna stabilnosti kosina.
Različite metode i načini proračuna često imaju za posljedicu i različite faktore sigurnosti za
kosinu uz pretpostavku istih parametara tla i geometrijskih uvjeta. Cilj istraživanja bio je
usporediti faktore sigurnosti radnih i završnih kosina koristeći tri različite metode, dvije
računalne, te jednu tabličnu. Korištene metode su pojednostavljena Bishopova metoda
korištena pri računalnoj i tabličnoj obradi podataka, te Morgenstern-Priceova metoda. Za
računalnu obradu podataka korišten je program GeoStudio, Student licence koji na
jednostavan i efektivan način omogućuje izračunavanje željenih faktora sigurnosti služeći se
prethodno unesenim veličinama. Tablična obrada podataka provedena je u MS Excelu.
Rezultati analiza ukazuju da postoje manje razlike u dobivenim faktorima sigurnosti,
međutim ove razlike ne bi trebalo bitno utjecati na stabilnost kosina obzirom na primjenu
faktora sigurnosti.

Abstract (english)

Slope stability represents one of the major challenges in mining and geotechnics. With the development of
science and computers, numerous methods and ways of calculating the stability of the slopes have been
developed. Different methods and estimations often result in different safety factors for the slope with the
assumption of the same parameters of soil and geometric conditions. The aim of the research was to compare
the safety factors of working and finishing slopes using three different methods, two computer and one tabular.
The methods used are the simplified Bishop method used in computing and data processing and the
Morgenstern-Price method. For computer data processing, the GeoStudio Student License Program has been
used, which in a simple and effective way allows to calculate the desired security factors by using previously
entered values. Tabular data processing was performed using MS Excel. The results of the analysis indicate
that there are minor differences in the safety factors obtained, however, these differences should not
significantly affect the stability of the slope with regard to the application of safety factors.
