Abstract

U ovom diplomskom radu analizirala se stabilnost nasipa na pruzi M202 Zagreb-Rijeka koji se sanirao pomoću pilotne stijene i mlazno injektiranih stupnjaka. Numerička analiza je uključivala analizu stabilnosti i naponsko-deformacijsku analizu koje su provedene u programu GeoStudio, modulima SIGMA i SLOPE. Sanacija nasipa je provedena nakon što su se dugotrajnim praćenjem pomaka tla utvrdile prekomjerne deformacije. Nakon toga da bi se odredio način sanacije bilo je potrebno odrediti uzrok nestabilnosti, a zatim se i uz pomoć istražnih radova došlo do karakteristika tla koje čine predmetnu lokaciju. Odabirom relevantnih parametara tla za sanaciju nasipa pristupilo se analizi čiji su rezultati prikazani grafički te su još dodatno prikazani u sumarnim tablicama.

Abstract (english)

In this master thesis, the stability of the embankment on the M202 Zagreb-Rijeka railway was analyzed, which was repaired using pilot rock and jet-grouted coulomns. Numerical analysis included stability analysis and stress-strain analysis, which were carried out in the GeoStudio program, SIGMA and SLOPE modules. The remediation of the embankment was carried out after the long-term monitoring of soil movement revealed excessive deformations. After that, in order to determine the method of remediation, it was necessary to determine the cause of the instability, and then with the help of investigative work, the characteristics of the soil that make up the location in question were determined. By selecting the relevant soil parameters for embankment remediation, an analysis had started, the results of which are presented graphically and are additionally presented in summary tables.
