Structural analysis of Jelezovac dam stepped spillway with baffle

Abstract

The concrete gravity dam spillway on the Jelezovac stream is presented. The overflow section of the dam is an original structure, designed as a stepped spillway, with bottom outlets and the modified USBR VI stilling basin with a baffle. The structural design consisted of the general stability computation, and the design of the basin elements was based on the hydrodynamic load, obtained from the hydraulic computations.

U radu je prikazana statička analiza prelivne lamele gravitacione betonske pregrade na potoku Jelezovac. Prikazana lamela je originalno rešenje, projektovana kao stepenasti preliv sa propustima i umirujućim bazenom, koji predstavlja modifikovani tip slapišta USBR VI sa odbojnom gredom. Statičkom analizom je obuhvaćena opšta stabilnost pregrade i dimenzionisanje elemenata slapišta, pri čemu su hidrodinamička opterećenja procenjena na osnovu proticaja i brzina dobijenih hidrauličim proračunom.
