Abstract

Ovaj rad razrađuje geotehnički projekt mosta Komari. Most Komari je jedan od 7 mostova što se grade u sklopu rekonstrukcije pruge Koprivnica – Križevci – Mađarska granica. Kao riješenje temeljenja je odabrano temeljenje na armiranobetonskim bušenim pilotima, koji se izvode u koherentnom tlu. Proračun pilota obuhvaća proračun nosivosti pilota na vertikalno opterećenje i proračun slijeganja pilota. Cilj je dokazati da odabrana geometrija pilota zadovoljava granična stanja prema Eurokodu 7. Osim pilota, proračunava se i slijeganje tla ispod nasipa. Tlo je koherentno i sporo konsolidira. Kao tehničko rješenje poboljšanja tla su odabrani šljunčani piloti. Proračunava se konsolidacijsko slijeganje za određen broj dana. Svi proračuni su provedeni u alatima iz paketa računalnih programa Rocscience. Naglasak rada je proračun, no zastupljene su i teorijske pozadine proračuna, kao i teorija i tehnologija izvođenja navedenih geotehničkih konstrukcija i poboljšanja tla.

Abstract (english)

This thesis analyzes the geotechnical design of the Komari bridge. The Komari bridge is one of the 7 bridges constructed as a part of the „Koprivnica – Križevci – mađarska granica“ railway reconstruction. Reinforced concrete bored piles were chosen as the bridge foundations, wich are bore din coherent soil. The main goal is to prove that the chosen pile geometry mets the load capacity and allowed settlement per Eurocode 7. In addition to the piles, the ground settlement under the embankment is also calculated. The soil is coherent, therefore it consolidates at a slow rate. Gravel piles were chosen as a technical solution for soil improvement unde the embankment. Consolidation settlement is calculated for a certain number of days. All calculations were carried out in tools from the Rocscience software package. The emphasis of the paper is calculation, but the theoretical background of calculation is also represented, as well as the theory and technology of execution of the mentioned geotechnical constructions and soil improvement.
