Abstract:Gradnja premostitvenih objektov z metodo postopnega narivanja je vedno bolj razširjena, še posebej na terenih s težko dostopnostjo, neugodno geološko sestavo in za gradnjo objektov z večjimi razponi med stebri. V diplomski nalogi v uvodu spoznavam širše vidike mostogradnje s poudarkom na razvoju metode gradnje z monolitnimi strukturami, ki so skozi leta prešla v postopno narivanje prednapetih armiranobetonskih mostov. Bistvo te metode je lokalizirana gradnja celotne prekladne konstrukcije v delavnici, ki ji periodično sledi postopno narivanje na zgrajene stebre in opornike. Na prvi pogled razmeroma enostaven način tovrstne gradnje pa zahteva vpeljavo dodatnih kablov v prekladno konstrukcijo, ki prevzamejo napetosti v konstrukciji, ki se pojavijo med in po končanem narivanju. Kot spoznavam v eksperimentalnem delu pri gradnji viadukta 6-2 Ponikve, je elegantna logistika podkrepljena še z natančnimi meritvami in posebej prilagojeno opremo, ki so značilni za takšno gradnjo.

Title:THE CONSTRUCTION TECHNOLOGY OF THE VIADUCT 6-2 PONIKVE
Abstract:The construction of bridges using the method of incremental launching is expanding especially when dealing with difficult terrains with weaker geological properties and by building structures with larger spans between the piers. In the diploma I introduce wider aspects of bridge building with the accent on the development of methods that comprise big monolithic structures which evolved through the years in the incremental launching of prestressed concrete superstructure. The core of the method is localized construction of the entire structure in the workshop with periodical incremental launching of the growing structure on pillars and piers. Seemingly simple construction technique includes in reality the introduction of additional suspension cables in the construction that play the crucial role of opposing the additional stresses in the superstructure during launching and provide the necessary support in the final position of the composition. As I discover in the experimental part at the construction of the viaduct 6-2 Ponikve the elegant logistics is supported also with accurate measurements and specially developed launching equipment that is typical for this kind of bridge building technique.
