Abstract

Neizravno djelovanje toka vode predstavlja opasnost za mehaničku otpornost mostova jer erozivnim djelovanjem vode utječe na konstrukciju mosta odnosno mijenja geometriju postojećeg projektnog stanja i time ju izlaže novim uvjetima opterećenja. U radu se analizira upornjak mosta s različitim kutom otklona u uzdužnom smjeru kako bi se analizirala pojava vrtloga oko temelja mosta u uvjetima bistre vode. Provedeno je eksperimentalno ispitivanje u pravokutnom otvorenom kanalu laboratorija Zavoda za... More Hidrotehniku. Na kraju rada prikazani su rezultati izmjerenih hidrauličkih (brzina toka, dubina toka i protok) i morfoloških varijabli (batimetrija korita). Less

Abstract (english)

Indirect action of flow poses a risk to mechanical resistance as it results in scouring of structure, i.e. it changes the geometry of the existing design state and thereby subjects it to new loading conditions. Abutment of bridge with different alingment in the longitudinal directions are investigated under clear water conditions to observe scour generation around bridge foundations. The experimental study is performed in a rectangular open channel in laboratory of water research department.... More This paper presents the results of measured hydraulics (velocity, depth and flow) and morphological variables (bathymetry). Less
