Abstract

Premostitveni objekti spadajo med gradbeno inženirske objekte, ki predstavljajo enega ključnih elementov cestne infrastrukture. Ti objekti so največkrat najdražji, najpomembnejši in najobčutljivejši deli cest, zato jim je potrebno posvetiti veliko pozornost ne samo v fazi načrtovanja in gradnje, pač pa tudi v fazi njihove uporabe. Mostovi so v svoji življenjski dobi izpostavljeni negativnim vplivom, kot so prekomerne obremenitve, neugodni klimatski pogoji, površna izvedba in slabo vzdrževanje. Zahteve povezane z nosilnostjo, trajnostjo in varnostjo pa se s časom povečujejo. Da bo objekt trajno in varno služil svojemu namenu, ga moramo redno vzdrževati. V diplomski nalogi obravnavamo dve varianti sanacije mostu čez reko Savo v Podnartu. Ugotovljene poškodbe pri rednem in podrobnem pregledu objekta so zahtevale čim hitrejšo sanacijo v obliki ojačitve konstrukcije. Izbirali smo med ojačitvijo z lepljenjem karbonskih lamel in do-betoniranjem dveh armiranobetonskih nosilcev pod prekladno konstrukcijo. Obe možnosti smo primerjali tehnološko in stroškovno. Na koncu smo s pomočjo večkriterijskega odločanja z metodo analitičnega hierarhičnega procesa ocenili boljšo izmed obeh variant na podlagi stroškov, trajnosti objekta, časa sanacije in estetske vrednosti. Izbrani ukrepi morajo biti namreč vedno ekonomsko in časovno sprejemljivi ter trajnostni, saj le tako zadostijo zahtevam upravljavca in uporabnika.

Secondary title:	Analysis of rehabilitation project - bridge over Sava river in Podnart
Secondary abstract:	Bridging structures are civil engineering facilities that represent one of the key elements of the road infrastructure. They are often considered as the most expensive, the most important and the most delicate parts of the roads, which is why they should be given particular attention not only during the design and construction stages but also during the use-phase. During their lifetime, bridges are exposed to negative impacts, such as excessive loads, unfavourable climatic conditions, careless construction and poor maintenance. However, requirements related to their load capacity, sustainability and safety increase regularly with time. In order to ensure that the facility serves its purpose in a safe and sustainable way, it needs to be maintained on a regular basis. The thesis introduces two renovation solutions of the bridge over the river Sava in the village of Podnart. Through regular and detailed monitoring of the facility, damages were identified that required a rapid renovation in the form of construction reinforcement. It needed to be chosen between the reinforcements through bonding carbon lamellas or concreting two additional reinforced concrete beams under the deck construction. Both solutions have been compared in terms of technology and costs. With the help of multiple-criteria decision-making through analytic hierarchy process method, the better of the both solutions has been chosen in the light of costs, sustainability of the bridge, renovation time and aesthetic value. In order to fulfil the requirements of both the operator and the user, the selected measures always need to be acceptable in terms of costs as well as time.
