20.500.12556/RUL-86004 Uporaba optičnih kablov za spremljanje propustnosti energetskih nasipov diplomska naloga The use of optical fiber cables for monitoring the permeability of dikes V diplomski nalogi so najprej predstavljeni energetski nasipi, njihova oblika, zgradba in način delovanja. Razložene so osnove teoretičnega ozadja precejanja vode skozi telo nasipa in porušni mehanizmi, ki jih lahko takšen proces povzroči. V nadaljevanju so predstavljeni optični kabli in načela njihovega delovanja pri spremljanju precejanja. Metoda temelji na podlagi termičnih procesov v nasipu, saj voda vpliva na njegovo temperaturno stanje. Z optičnimi kabli tako merimo temperaturo, s čimer lahko natančno določimo lokacijo in stopnjo precejanja. Čeprav je metoda relativno nova, je že prešla v praktično uporabo in eden izmed primerov je tudi energetski nasip na hidroelektrarni Brežice. Naredili smo študijo propustnosti tega nasipa in analizirali tri različne primere. V prvem smo predpostavili, da je nasip homogen, v drugem smo obravnavali nasip v dejanski obliki, v tretjem pa smo predpostavili, da je tesnilna membrana poškodovana, kar smo modelirali z zvišanjem njene propustnosti. Rezultati so pokazali potek vodne gladine, s čimer smo lahko ovrednotili ustreznost zgradbe nasipa in pozicijo vgrajenih optičnih kablov. In the thesis we firstly introduce dikes, their form, structure and the way of functioning. Theoretical bases of seepage and modes of failure, which can be caused by such a process, are explained. Further, optical fiber cables and the principle of their functioning in the monitoring of seepage are introduced. The method is based on thermal processes in a dike, because water affects its temperature conditions. By measuring the temperature using optical fiber cables the location and the rate of seepage can be accurately determined. Although the method is relatively new, it has already come into practical use, and one of the applications is present at the dike of the hydroelectric power plant Brežice. We made a study of permeability of the dike and analysed three different cases. In the first case we presupposed that the dike is homogeneous, in the second one we treated the real dike, and in the third one we presupposed that the sealing membrane is damaged, which we modelled by increasing its permeability. The results showed the phreatic surface which enabled us to evaluate the form suitability of the dike and the position of optical fiber cables. gradbeništvo diplomska naloga B-GR optični kabli propustnost precejanje precejna krivulja energetski nasipi hidroelektrarna Brežice graduation thesis optical fiber cables permeability seepage phreatic surface dikes hydroelectric power plant Brežice true false false [R.
