Abstract

Diplomsko delo predstavlja možne izvedbe tlačnega cevovoda črpalne hidroelektrarne. Opisani so glavni sestavni deli cevovoda, njihovo delovanje, sestava in obrementive, ki jih prenašajo. Nadalje je predstavljen koncept tunelske gradnje po Novi avstrijski metodi gradnje in TBM. Podani so načini izboljšanja tal v okolici izkopa in vrste podpornih sistemov. Sledi izračun betonske, jeklene in sovprežne podzemne konstrukcije cevovoda v šestih različnih vrstah hribine, upoštevaje notranji pritisk v cevovodu. Prikazan je vpliv geomehanskih lastnosti tal na debelino obloge. Za primerjavo smo dodali površinski jekleni cevovod na podporah kot primer, kjer cevovod nima odpora hribine in mora obloga v celoti prenesti nastale obremenitve.

Secondary title:	Geomechanical analysis of pressure pipeline for pumped hydropower plant
Secondary abstract:	The thesis presents possible implementations of the pumping hydroelectric power plant’s pressure pipeline. Described are the main components of the pipeline, their functions, structure and the load, they can carry. Further on we present the concept of the tunnelling construction after the New Austrian Tunnelling Method and TBM. Presented are ways to improve the ground in the surroundings of the excavation and types of support systems, followed by the calculation of the concrete, steel and composite underground construction of the pipeline in six different types of grounds under the force of the internal pressure. It is presented the impact of geomechanical characteristics of the ground on the thickness of the shell. For the comparison we added a surface steel pipeline on supports as an example, where the pipeline has no resistance from the ground and the shell has to fully hold the given pressures.
