Abstract

Tema ovog diplomskog rada je usporedba različitih metoda proračuna poboljšanja tla ispod željezničkih nasipa. U radu su objašnjeni osnovni pojmovi vezani za ponašanje tla, šljunčani stupnjaci te je prikazan model poboljšanja temeljnog tla ispod vijadukta Carevdar. Proračun je proveden koristeći program Settle3 i Stonec koji se temelje na dvije različite metode. Cilj korištenih metoda je da se poveća nosivost tla, smanji ukupno i diferencijalno slijeganje te ubrza konsolidacija tla. Predstavljene su osnovne teoretske postavke vezane za profil tla te prikazani rezultati proračuna pomoću dvije različite metode.

Abstract (english)

The topic of this thesis is a comparison of different calcuation for soil improvement under railway embankments. The paper explains the basic therms related to soil behavior, stone columns presents a model for the improvement of the foundation soil under the Carevdar Viaduct. The calculation was carried out using the Settle3 and Stonec programs, which are based on two different metods. The aim of the methods used is to increase the bearing capacity of the soil, reduce total and differential settlement and accelerate soil consolidation. The basic theoretical settings related to the soil profile are presented, as well as the calculation results obtained using two different methods.
