Abstract

Tema diplomskog rada je nasip na željezničkoj pruzi M202 Zagreb-Rijeka, gdje je na lijevom dijelu nasipa uočena nestabilnost u duljini od 15 m. S obzirom na to da je do klizanja došlo uslijed gubitka posmične čvrstoće, gdje je uslijed saturacije tla došlo do smanjenja efektivnih naprezanja, ovaj rad obrađuje sanaciju predmetnog nasipa. Privremeno rješenje je dano izvedbom mikropilota, a trajne mjere sanacije uključuju uklanjanje materijala klizišta, te iskop prema geometrijskim pravilima, nakon čega se izvodi zamjena materijala nekoherentnim materijalom. U nožici nasipa se izvodi gabionska konstrukcija. Svrha ovog diplomskog rada je provesti potrebne numeričke analize kako bi se omogućilo sigurno izvođenje i funkcionalnost predviđene sanacije nasipa. U uvodnom dijelu se opisuje trenutno stanje na terenu s pripadajućom fotodokumentacijom i uvodom u problematiku. Rad se zatim nastavlja s poglavljem metoda stabilizacije klizišta, nakon čega slijedi poglavlje razrade geotehničkih podloga, prikaz rezultata istražnih radova i odabir relevantnih parametara. Potom slijedi geotehnički proračun s prikazom naponsko-deformacijske analize projektnog rješenja, te prikaz analize stabilnosti nasipa za odabrane proračunske situacije. Rad završava s prikazom tehničkih uvjeta izvedbe i programom kontrole kvalitete, zaključkom i popisom korištene literature.

Abstract (english)

This thesis analyses the railway embankment located on the line M202 Zagreb-Rijeka, where the instability occurred on the left part of the embankment in the length of 15 m. Since sliding has been caused by a loss of shear strength, where effective stresses have been reduced due to saturation of the soil, this thesis deals with embankment remediation. The temporary solution was given by the execution of micropiles, and permanent remedial measures include removal of landslide material and excavation according to geometric rules, after which the material is replaced by non-coherent material. At the bottom of the embankment, a gabion structures is executed. The purpose of this thesis is to perform the necessary numerical analyzes to enable the safe execution and functionality of the embankment reconstruction measures. The introductory section describes the current situation on the site with the accompanying photo documentation and introduction to the relevant issues. After the introduction, the thesis continues with the chapter on landslide stabilization methods, followed by the section on the analysis of geotechnical investigation works and selection of relevant parameters. This is followed by a geotechnical calculation showing the stress-strain analysis of the design solution and the analysis of the embankment stability in the selected design situations. The paper concludes with a presentation of the technical conditions of performance and a quality control program, a conclusion and a list of used literature.
