САЖЕТАК / ABSTRACT:

Šumski ekosistem koji se razvijaju na padinama, utiču na stabilnost svojim nadzemnim i podzemnim delovima. Kako se korenov sistem razvija, on zbija čestice zemljišta u jednu monolitnu masu, koju nazivamo bioarmiranim zemljištem, i time utiče na povećanje kohezije zemljišta čime se postiže povećanje stabilnosti padina. Šumski ekosistem kao živi sistem razvija se u vremenu i prostoru, i kao takva sklona je promenama.  Otpor biljnih vrsta na sile smicanja može se vremenom i smanjivati, posebno nakon ekstremnih događaja kao što su suša, požari ili čista seča šuma. Pored pozitivnog efekta na stabilnost padina, šumski ekosistem svojom masom vrši dopunsko opterećenje koje može uticati na smanjenje stabilnosti padina. U radu za pripremljeni model terena, analizirana je stabilnost u dva scenarija:  1) model terena je bioarmiran i opterećen masom vegetacije 2) nakon šumskog požara. Za sve analize stabilnosti modela terena korišćen je softver za geotehničko numeričko modeliranje GeoStudio 2024. Rezultati su pokazali da je uvođenjem parametra bioarmiranog tla i ravnomernog opterećenja od mase vegetacije u proračun stabilnosti, model terena stabilan. Prikazani rezultati prikazuju značaj biološke komponente prilikom izbora parametara za analizu stabilnosti padina i mogućnosti primene vegetacije kao jednog od rešenja za stabilizaciju padina.
