Abstract

Tema ovog diplomskog rada je temeljenje nadvožnjaka Pavučnjak za potrebe osiguranja prijelaza u km 21+940 preko željezničkog kolosijeka pruge M202 Zagreb GK-Rijeka. Kao način temeljenja odabrano je duboko temeljenje na AB bušenim pilotima. Temeljenje se izvodi u tlu kojeg čine dva sloja gline (C) između kojih se nalazi sloj glinovitog pijeska/glinovitog šljunka (SC/GC). Kroz analize uzdužne i poprečne nosivosti grupe pilota za najopterećenije stupno mjesto i najopterećeniji upornjak te kroz analizu slijeganja i bočnog pomaka dokazati će se zadovoljenje graničnih stanja. Kroz rad je opisano trenutno stanje predmetne lokacije te odabrano rješenje. Rad se nastavlja sa općim opisom odabranog dubokog temeljenja i projektiranje pilota prema Eurokod normi. Nakon razrade podloga i odabira relevantnih parametara potrebnih za analize, u radu slijedi geotehnički proračun odabranog projektnog rješenja. Rad završava prikazom tehničkih uvjeta izvedbe i programom kontrole kvalitete, zaključkom i popisom korištene literature.

Abstract (english)

This thesis analyses the foundations of the Pavucnjak overpass for the purpose of securing the crossing in km 21+940 of the railway line M202 Zagreb GK-Rijeka. A deep foundation on the AB bored piles was chosen. The foundation is performed in soil consisting of two layers of clay (C) between which there is a layer of clayey sand/clayey gravel (SC/GC). Through the analysis of the longitudinal and transverse load capacity of the group of pilots for the most loaded pier and the most loaded abutment, and through the analysis of subsidence and lateral displacement, the satisfaction of the limit state is proven. The work describes the current state of the location and the selected solution. The work continues with a general description of the selected deep foundation and the design of the piles according to Eurocode standards. After elaborating the substrates and selecting the relevant parameters necessary for the analysis, the work follows the geotechnical calculation of the selected design solution. 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.
