Abstract
U okviru ovog diplomskog rada provedena su laboratorijska ispitivanja kojima se pratilo procjeđivanje kroz modele nasute brane manjeg mjerila, s ciljem analiziranja stabilnosti takvih objekata. Izgrađena su dva modela homogene brane nagiba pokosa 1:1,3 i 1:2, koristeći riječni (dravski) pijesak poznate granulacije. Svi model izgrađeni su na nepropusnoj podlozi. Za provedbu ovih ispitivanja korišten je fizikalni model HM 169 kojim se regulirala brzina punjenja rezervoara i visina gornje vode pri čemu se pratilo formiranje procjedne linije. Na temelju dobivenih podataka izrađeni su numerički modeli koristeći računalni program GeoStudio 2024.1.0. Pomoću Seep/W analize simulirano je procjeđivanje vode kroz tijelo brane kroz točno određeno vrijeme te su tako dobiveni porni tlakovi korišteni kao ulazni parametri za Slope/W analizu, kako bi se mogla analizirati stabilnost pokosa, potencijalne klizne plohe i pripadajući faktori sigurnosti. Model s nagibom pokosa 1:2, što je ujedno i preporuka za izgradnju ovakvih objekata, pokazao je izdržljivost i mogućnost da se odupre postavljenim uvjetima, dok se kod modela sa strmijim nagibom pokosa (1:1,3) javio slom. Kako bi i drugi model zadovoljio stabilnost, poduzete su dodatne mjere u vidu ojačanja modela geotekstilom te je i takva situacija modelirana u računalnom programu GeoStudio 2024.1.0.
Abstract (english)
In this study, laboratory tests were conducted to monitor seepage through the small-scale embankment dam model, with the aim of analyzing the stability of such structures. Two models of homogeneous dams with slopes of 1:1.3 and 1:2 were constructed using river (Drava) sand of known grain size. All models were built on an impermeable base. The HM 169 physical model was used for these tests, regulating the reservoir filling rate and the upstream water level while monitoring the formation of the seepage line. Based on the obtained data, numerical models were created using the GeoStudio 2024.1.0 software. The Seep/W analysis simulated water seepage through the dam body over a specified period, and the resulting pore pressures were used as input parameters for the Slope/W analysis to analyze the slope stability, potential slip surfaces, and corresponding safety factors. The model with a 1:2 slope, which is recommended for the construction of such structures, demonstrated resilience and the ability to withstand the set conditions, whereas the model with a steeper slope (1:1.3) experienced failure. To ensure the stability of the second model, additional measures were taken by reinforcing the model with geotextile, and this scenario was also modeled using the GeoStudio 2024.1.0 software.
