Secondary title: Construction of dikes from using sand as main fill material - feasibility study
Secondary abstract: HE Breţice is the fifth in a chain of six hydroelectric power plants on the lower Sava. Approximately 13 km of dikes will have to be built along the left and the right bank of the Sava river to create an accumulation reservoir. In my degree we examined the possibility to use locally available sand deposits as the main fill material. The use of sand will represent the environmentally and economically friendly solution. Because there is no experience in building dikes from sands in Slovenia and this sand has a reputation of being difficult to build dikes from, we examined characteristics of sand and estimated its application in dikes. We examined all index properties of sand, the compactibility, deformability, collapse, shear strength and permeability. The results of laboratory tests were verified by control measurements at the experimental dike built of local sands. The analysis of the results showed that the sand could be used as fill material, however some requirements regarding the achieved dry density and the use of filters layers to prevent piping must be fulfilled.

Abstract (ePrints): HE Breţice je peta hidroelektrarna v verigi šestih hidroelektrarn na spodnji Savi. V sklopu izgradnje HE Breţice se bodo vzdolţ reke Save za potrebe izgradnje akumulacijskega bazena gradili energetski nasipi v skupni dolţini cca. 13 km. V diplomski nalogi smo preverili moţnosti gradnje energetskih nasipov iz lokalno razpoloţljivih peskov, saj bo takšna gradnja predstavljala ekonomično in okolju prijazno rešitev. Ker v Sloveniji nimamo izkušenj z gradnjo nasipov iz peska in le ti veljajo za problematične materiale, smo v laboratoriju preiskali lastnosti peska in ocenili njegovo vgradljivost v energetske nasipe. Pri tem smo preiskali indeksne kazalnike peskov, vgradljivost, deformabilnost, kolaps, striţno odpornost in prepustnost. Rezultate laboratorijskih preiskav smo preverili s kontrolnimi meritvami na poskusnem nasipu zgrajenem iz lokalnih peskov. Analiza rezultatov laboratorijskih in terenskih raziskav je pokazala, da je gradnja nasipov z uporabo lokalnih peskov moţna, vendar le z upoštevanjem določenih zahtev glede potrebne zgoščenosti in rabe filtrov za doseganje filtrske stabilnosti.
