Vpliv razpokanosti na varnost betonskih težnostnih pregrad : diplomska naloga

Adamič, Andrej (author), Schnabl, Simon (mentor), Kryžanowski, Andrej (co-mentor)

V diplomski nalogi so predstavljene betonske pregrade in vzroki za nastanek razpok v njih. Predstavljena je tudi zgodovina in energijska zmogljivost hidroelektrarne Moste ter njena mehanska analiza z računalniškim programom CADAM. S programom CADAM je bila določena varnost HE Moste in sicer za različne nivoje razpokanosti pri različnih obtežnih kombinacijah, drenažnih modelih, višinah in naklonih razpok in vrednostih povprečnih horizontalnih pospeškov tal. Poleg tega so bile na osnovi zahtevanih varnostnih faktorjev za zdrs izračunane dopustne dolžine razpok v vseh treh obravnavanih obtežnih kombinacijah. Ugotovljeno je bilo, da ima razpokanost pomemben vpliv na samo varnost pregrade.

• Title: The influence of cracking on safety of concrete gravity dams

Abstract

In the thesis, the influence of cracking on safety of concrete gravity dams has been analysed. This influence has been studied on the case study of hydroelectric power plant Moste. The mechanical analysis has been performed with a computer program CADAM. The safety of the Moste dam has been analysed for various load combinations, drainage systems, crack heights, and values of horizontal ground accelerations. It has been proved that cracking has an important influence on safety of Moste concrete gravity dam.
