Examples of landslide stabilization costs on the road infrastructure

Pri sanaciji klizišta, pojave koja je veoma česta na putevima Srbije, brojne su nepoznanice kod procene troškova radova predviđenih za njihovu stabilizaciju. Veoma su važni uticajni činioci većeg broja promenljivih (kojima se opisuju svojstva terena i dimenzije kliznog tela) na cenu konstrukcije pri saniranju klizišta. Takođe, građevinski zahvati koji se izvode u cilju poboljšanja stabilnosti padina su dosta raznovrsni, što uz različite uzroke pojave klizišta i njihove elemente, ima za posledicu široke raspone utrošenih sredstava po sanaciji. Kako je apsolutno neophodno stabilizovati ugrožene saobraćajnice ili druge objekte na nestabilnim terenima, veoma je važno, svakako i za našu državu, racionalno korišćenje sredstava koja se opravdano izdvajaju u tu svrhu. Landslides are frequent natural hazard occurrence on the road network in Serbia. During their stabilization, there are usually uncertainties regarding stabilization work price evaluation. Conditioning factors of numerous variables (that are describing the terrain properties and landslides dimensions) which are affecting the final price of stabilization are of great importance. Also, construction works that are usually performed for the purpose of slope stabilization are various, and when they are combined with different landslide triggering factors and their elements - as a consequence we have a significant discrepancy of funds that are spent for stabilization. Since absolute stabilization of landslides that are occurring across infrastructure and other objects on unstable slopes is necessary, it is very important for each country and Serbia as well to rationalize the use of budget funds that are allocated for that purpose.
