Abstract

U diplomskom radu analizirana je zaštita građevnih jama uređaja za pročišćavanje otpadnih voda u Varaždinu. U uvodnom su dijelu općenito prikazani različiti sustavi zaštite građevnih jama. Nakon toga prikazan je odabir proračunskih vrijednosti parametara materijala na temelju rezultata terenskih i laboratorijskih istražnih radova. Uzimajući u obzir visoku razinu podzemne vode i uglavnom šljunčana tla s visokim koeficijentom propusnosti, primijenjeno je rješenje zaštite građevne jame i brtvljenje dna metodom mlaznog injektiranja. Provedeni su proračuni u programu GeoStudio: naponsko-deformacijske analize i analize procjeđivanja temeljene na metodi konačnih elemenata, te analize stabilnosti temeljene na metodi granične ravnoteže. Također je provjerena i stabilnost svih objekata na uzgon. Na kraju je prikazan program kontrole kvalitete tijekom izvođenja radova

Abstract (english)

This master’s thesis analyses protection of the construction pit of wastewater treatment plant Varaždin. The introductory section describes various construction pit protection methods. This is followed by selection of design soil parameters based on the results of field and laboratory tests. Considering high groundwater levels and mainly gravelly type soils with a high permeability coefficient, jet-grouting method for protection of construction pits and sealing of the excavation bottom level was applied. Numerical analyses using GeoStudio software were performed: stress-strain analyses and seepage analyses based on finite element method, and stability analyses based on limit equilibrium method. Uplift verification analysis was also performed. The thesis concludes with suggested quality control program for the construction phase.
