Račun vala vsled morebitne porušitve pregrade Loče : diplomska naloga

Mavc, Borut (author), Četina, Matjaž (mentor)

V diplomski nalogi sem se ukvarjal z računom porušitvenega vala ob morebitni porušitvi pregrade Loče. Val sem računal s pomočjo programa HEC-RAS, ki lahko za izračun uporablja različne enačbe, odvisno od izbire uporabnika. Dve vrsti, ki sta na, razpolago so polne dinamične enačbe ter poenostavljene dinamične enačbe. V uvodnem teoretičnem delu sem se dotaknil samih pregrad ter porušitvenih valov. Podal sem tudi osnovne enačbe, ki se v hidravliki uporabljajo za račun valov. Sledi opis obravnavanega območja in ugotovitve s terenskega ogleda pregrade. Dodane so avtorske slike, posnete na terenskem ogledu. V zaključnem delu naloge so podani rezultati za vsak računski primer posebej. Na koncu je opravljena tudi primerjava z rezultati izračunov projekta VODPREG 2. V zaključku so podane prednosti in pomanjkljivosti obeh uporabljenih programov.

• Title: Calculation of the wave due to possible colapse of the Loče dam : Graduation thesis

Abstract

In my diploma, I dealt with the calculation of a dam-break wave due to possible collapse of the Loče dam. I calculated the wave using the HEC-RAS programme, which can use different equations to calculate, depending on the user's choice. Two types that are available are full dynamic equations and simplified dynamic equations. In the introductory theoretical part, I mentioned the dams themselves and the dam-break waves. I also provided the basic equations that are used in the hydraulics for the calculation of waves. This is followed by a description of the area under consideration and findings from the field inspection of the dam. Copyright images taken on the field inspection are added. In the final part of the diploma, the results for each case are given separately. A comparison with the results of the project VODPREG 2 calculations has also been made. Advantages and disadvantages of the two programmes used are given in the conclusion.
