Abstract
The influence of converging stepped spillways on the dimensions of the stilling basins for RCC dams was examined, based on the results of physical modeling, existing empirical expressions, and basic laws of fluid mechanics and hydraulics. The study includes analysis of parameters that affect the magnitude of the hydrodynamic force which is transferred into the stilling basin, and presents an original design methodology. Analysis of the measured data and the methods for estimation of the sequent depth in the stilling basin are presented, with recommendations for design purposes and future studies.
Cilj rada je da se na osnovu zakona mehanike fluida, postojećih rezultata modelskih ispitivanja i empirijskih izraza, analizira uticaj neprizmatičnosti stepenastog brzotoka na potrebne dimenzije umirujućih bazena kod gravitacionih betonskih brana. Analizirani su parametri koji utiču na sile od vode na ulasku u umirujući bazen, na osnovu kojih je predložena metodologija za dimenzionisanje umirujućih bazena. Na osnovu merenja na fizičkom hidrauličkom modelu, upoređeni su rezultati proračuna razmatranih metoda i na osnovu njih date preporuke, kako za projektovanje, tako i za buduća istraživanja.
