PRELIMINARY DESIGN OF RESERVOIR AND EARTH DAM ČITLUK

Diplomskim radom predloţeno je idejno rješenje akumulacije i zemljane nasute brane na potoku Čitluk u Vukovarsko-srijemskoj ţupaniji. Za izradu rada korištene su: geodetske, prostorno planske, hidrološke i geomehaničke podloge uz pomoć kojih se pristupilo hidrološkoj, hidrauličkoj i geomehaničkoj analizi. Na temelju maksimalnih protoka 100. i 1000. godišnjih povratnih razdoblja odreĎen je radni volumen akumulacije i zemljane nasute brane koja će se smjestiti na rkm 3 + 386 potoka Čitluk. Provedeno je dimenzioniranje brane s pripadnim graĎevinama (preljev, temeljni ispust, slapište). Uz pomoć programskog paketa Geostudio (SLOPE/W, SEEP/W, SIGMA/W) provedene su analize stabilnosti, proračun procjeĎivanja kroz nasutu branu i naponsko - deformacijska analiza za navedenu branu. Proračun stabilnosti proveden je za slučajeve statičkog i dinamičkog opterećenja. Na temelju provedenih analiza i proračuna utvrĎene su optimalne dimenzije i svojstva brane zadane projektnim zadatkom.The thesis proposes a preliminary design of the storage reservoir and earthfill dam on Čitluk Creek in the Vukovar-Srijem County. In this thesis, geodetic surveying, physical planning, hydrological and geomechanical bases were used to conduct hydrological, hydraulical and geomechanical analyses. On the basis of a peak flow of a 100- and 1000-year recurrence interval, the operating volume of the storage reservoir and earthfill dam, which will be constructed at 3 + 386 RK of Čitluk Creek, was determined. Dimensioning of the dam and related structures (spillway, bottom outlet, stilling basin) was carried out. The GeoStudio software suite (SLOPE / W, SEEP / W, SIGMA / W) was used to perform stability analysis, calculation of seepage (through the earthfill dam and foundation soil), and stress-strain analysis for the said dam. The stability calculation was carried out for the cases of static and dynamic loading. On the basis of all performed analyses and calculations, the optimal dimensions and properties of the dam set by the project assignment have been determined
