V sklopu diplomskega dela sem se seznanjala z vplivi eksplozij na vodne pregrade. Naredila sem zgodovinski pregled napadov na vodne pregrade in njihove poškodbe. Na podlagi pregleda dosegljive literature s tega področja sem se usmerila na učinek udarnega vala, ki ga povzroči eksplozija. Posebej sem obravnavala podvodni udarni val in njegov vpliv na betonsko težnostno pregrado ter pri tem opisala poškodbe učinka udarnega vala. Izvedla sem statično analizo v računalniškem programu CADAM v katerem sem namesto dinamične obremenitve eksplozije uporabila nadomestno statično obtežbo udarnega vala. Ugotovila sem, da ima mesto in količina eksplozivnega materiala pomemben vpliv na varnost obravnavane pregrade. In the thesis, the influence of underwater explosion on safety of concrete gravity dams has been analysed. Moreover, a historical overwiew of various attacks on different dams and their failures has been made based on the available literature. A special attention has been given to the effects of shock wave caused by the explosion. A parametric study has been conducted in a computer program CADAM. The safety of concrete gravity dam Moste, which has been subjected to equivalent static load of the shock wave, has been analysed in detail. It has been found that the position and quantity of the explosive material has a significant influence on safety of concrete gravity dam.
