Abstract
Hydraulic design of shaft spillways (morning-glory spillways) with flow deflector before the vertical bend is considered. Based on the physical hydraulic model investigations of several structures and available experience of other authors, the key features, concerning capacity of the spillway, vertical shaft and tunnel-flow are defined and discussed. New expressions for discharge and velocity coefficients have been proposed, and some of the old ones improved. Also, a new procedure for the shaft design is proposed, including the spillway-to-shaft transition-reach definition. Finally, an algorithm for entire design procedure has been put forward.
Razmatrano je hidrauličko dimenzionisanje šahtnog preliva sa deflektorom ispred vertikalne krivine. Na osnovu hidrauličkih modelskih ispitivanja nekoliko objekata, kao i iskustva drugih autora, procenjeni su ključni činioci koji određuju propusnu sposobnost prelivnog, šahtnog i tunelskog dela objekta. Predloženi su novi i poboljšani raniji izrazi za procenu koeficijenata prelivanja, isticanja na deflektoru i koeficijenta brzine. Takođe, prikazan je i postupak za oblikovanje šahta, uključujući prelaznu deonicu između preliva i šahta. Na kraju se daje sažet algoritam celog postupka dimenzionisanja objekta.
