Abstract

U ovom radu rješavan je problem poboljšanja temeljnog tla ispod prijelazne rampe na dionici Križevci-Koprivnica na mostu Koprivnica1 u sklopu projekta poboljšanja postojećeg i izgradnje drugog kolosijeka željezničke Križevci-Koprivnica-Državna granica. Između više metoda izabrana je metoda poboljšanja tla šljunčanim stupnjacima, proračunom u softwareu Settle3 koji koristi ekvivalentnu homogenizacijsku metodu za zamjensku krutost i ekvivalentnu propusnost stupnjaka. Bitna stvavka je da dopušteno preostalo slijeganje bude manje od dopuštene granice unutar mjesec dana, jer radovi trebaju krenuti što prije. Provedeni su proračuni uspoređujući kako povećanje promjera stupnjaka utječe na konačne rezultate , također u zadnjem slučaju kako smanjenje osnog razmaka utječe na konačno slijeganje.

Abstract (english)

In this paper problem of improving the foundation soil below the transition ramp on the section Križevci-Koprivnica on the bridge Koprivnica1 was solved as part of the projcet to improve the existing and construction of the second railway track Križevci-Koprivnica-State bord. Among several methods, the method of soil improvement with gravel steps was chosen, calculated in the software Settle3, which uses the equivalent homogenization method for repleacement stiffness and equivalent permeability of the columns. Calculations were performed comparing how increasing the diamete of the columns affects the final results, also in the latter case how decreasing the axial spacing affects the final settlement.
