20.500.12556/RUL-183811 Eksperimentalna in računska analiza koeficienta vodoprepustnosti zemljine diplomska naloga Experimental and computational analasys of the hydraulic conductivity of soils graduation thesis V sklopu diplomske naloge smo eksperimentalno in računsko analizirali koeficient vodoprepustnosti zemljin. Laboratorijske preiskave smo izvedli na kraški glini in pesku, ter njunih mešanicah. Namen naloge je bil primerjati laboratorijsko izmerjene vrednosti koeficienta vodoprepustnosti z vrednostmi, ocenjenimi na podlagi empiričnih enačb, ter ovrednotiti vpliv zrnavostne sestave na dobljene rezultate. Poleg rezultatov, pridobljenih na laboratorijsko pripravljenih nabitih preizkušancih, smo analizirali tudi arhivske rezultate za intaktne vzorce drobnozrnatih zemljin. Na ta način smo lahko ocenili tudi vpliv postopka priprave preizkušanca (intakten, nabit) na rezultat meritve in na ocenjeno vrednost k. Rezultati kažejo, da se izmerjeni koeficient vodoprepustnosti z naraščanjem deleža gline zmanjšuje. Primerjava med izmerjenimi in posredno določenimi vrednostmi koeficientov vodoprepustnosti je pokazala, da empirične enačbe pogosto podcenjujejo vrednost koeficienta vodoprepustnosti, zlasti pri nabitih vzorcih, medtem ko je bilo ujemanje pri intaktnih vzorcih praviloma nekoliko boljše. Na podlagi rezultatov smo ugotovili tudi, da so empirične enačbe primerne predvsem za orientacijske ocene koeficienta vodoprepustnosti, ne morejo pa nadomestiti ciljanih terenskih in laboratorijskih preiskav, prilagojenih naravi zemljine in namenu uporabe rezultatov. Empirične zveze so bile namreč razvite na podlagi omejenih nizov podatkov za določene tipe zemljin, zato imajo omejeno področje uporabnosti, posledično pa je omejena tudi zanesljivost izračunanih vrednosti koeficienta vodoprepustnosti. In this thesis, the coefficient of hydraulic conductivity of soils was analysed experimentally and computationally. Laboratory tests were carried out on karst clay, sand and mixtures of the two materials. The aim of the thesis was to compare laboratory-measured values of hydraulic conductivity with values estimated using empirical equations, and to evaluate the influence of grain-size distribution on the obtained results. In addition to the results obtained on laboratory-prepared compacted specimens, archival results for intact samples of fine-grained soils were also analysed. This made it possible to assess the influence of specimen preparation, namely intact and compacted specimens, on the measured and estimated values of hydraulic conductivity. The results show that the measured hydraulic conductivity decreases with increasing clay content. The comparison between measured and indirectly determined values of hydraulic conductivity showed that empirical equations often underestimate hydraulic conductivity, particularly for compacted specimens, while the agreement was generally somewhat better for intact samples. Based on the results, it was also found that empirical equations are mainly suitable for preliminary estimates of hydraulic conductivity and cannot replace targeted field and laboratory investigations adapted to the nature of the soil and the basis of limited data sets for specific soil types and therefore have a limited range of aplicability. Consequently, the reliability of the calculated values of hydraulic conductivity is also limited. diplomske naloge gradbeništvo koeficient vodoprepustnosti zemljina empirične enačbe laboratorijske preiskave graduation thesis civil engineering permeability coefficient soil empirical equarions laboratory tests true false false [L.
