Abstract:V magistrskem delu smo preučili načine tesnjenja in vrste pregradnih nasipov, ter opredelili, kateri način tesnjenja je najprimernejši pri našem pripraktičnem primeru izdelave dovodnega kanala za HE Hrastje-Mota na trenutno nereguliranem toku reke Mure. Zaradi lažjega razumevanja rezultatov in končnega izdelka so v magistrskem delu razloženi laboratorijski testi in rezultati preiskav, ki so potrebni za določitev optimalnega načina tesnjenja in za dimenzioniranja pregradnega nasipa. Obrazloženi so tudi nekateri principi precejanja vode skozi nasip in temeljna tla, načini zagotavljanja dovolj majhnih vodnih izgub ter predlog optimalnega načina tesnjenja in dimenzioniranja načrtovanih pregradnih nasipov ob reki Muri. Predložen je način kombiniranega tesnjenja z vertikalno tankostensko diafragmo v območju vodonosnika ter izgradnjo homogenega maloprepustnega nasipa za zadrževanje vode nad njo. Dokazano je, da je z mešanjem in zgoščevanjem gramoznih in peščeno meljnih zemljin mogoče izdelati dovolj vodotesno tesnilno mešanico, ki zagotavlja zmanjšanje vodnih izgub na zanemarljivo raven ob hkratnem izpolnjevanju zahtevanih projektnih pogojev, ki so določeni z veljavnimi predpisi in standardi. Cilj magistrskega dela, da je na osnovi rezultatov laboratorijskih preiskav mogoče utemeljiti optimalni način tesnenja narčrtovanih pregradnih nasipovna reki Muri in je bil po moji oceni v celoti dosežen.

Title:SEALING AND GEOTECHNICAL ASSESSMENT OF THE STABILITY OF EARTH EMBANKMENTS
Abstract:In this master work, we have explored the ways of sealing and types of earth embankments, and defined which type of sealing is the most appropriate in our case of building of the embankment on the currently unregulated flow of the Mura River. For easier understanding of the results and the final product, this master work will explain all the laboratory tests which we need to come up with an optimum sealing and dimensioning of the embankment. It also discusses the principle of the flow of water through the embankment and how optimally dimension and seal the future earth embankment on the Mura River. Presented is a combined method of a vertical thin-walled sealing diaphragm in the range of aquifer and the construction of a homogeneous embankment to retain water above it. It has been proved that by mixing and compaction of gravel and sand silty soils can be made sufficiently waterproof sealing mixture and it provides a reduction in water losses to negligible levels while meeting the required design conditions specified by current regulations and standards. The aim of the master work is to establish, on the base of laboratory tests, the optimal way of sealing of the planned earth embankments on the Mura River and, in my opinion, it was fully achieved.
Keywords:civil engineering, geotechnics, assessment of stability, sealing, flow of water, earth embankments
