Abstract

Izgradnja mosta Carevdar dio je projekta poboljšanja postojećeg te izgradnje drugog kolosijeka željezničke pruge M201 Državna granica – Botovo – Dugo Selo, na dionici Križevci – Koprivnica – Državna granica, dio koje je poddionica Križevci (isključivo) – Carevdar. U ovome radu potrebno je provesti analizu konsolidacije i pridruženog slijeganja temeljnog tla nasipa prilazne rampe mosta Carevdar. Izgradnji mosta može se pristupiti ako je zadovoljen uvjet da preostala slijeganja temeljnog tla nasipa ne budu veća od 5 cm. Projektom je uvjetovano i da s početkom gradnje mosta treba započeti mjesec dana nakon izgradnje nasipa. Nakon provedene proračunske analize, pokazalo se da traženi uvjeti nisu zadovoljeni te da je potrebno poboljšati tlo u vidu ugradnje šljunčanih stupova. Njihova ugradnja smatra se optimalnim rješenjem za ubrzanje procesa konsolidacije te smanjenje ukupnih slijeganja u sitnozrnatom tlu. Pri tome je vrlo važno ispravno ih dimenzionirati.

Abstract (english)

The construction of the Carevdar bridge is part of the project of improving the existing and construction of the second track of the M201 State Border - Botovo - Dugo Selo railway, on the section Križevci - Koprivnica - State Border, part of which is the subsection Križevci (exclusively) - Carevdar. In this paper, it is necessary to conduct an analysis of consolidation and settlement of the foundation soil of the embankment of the access ramp of the Carevdar bridge. The construction of the bridge can be approached if the condition is met that the remaining settlement of the foundation soil of the embankment does not exceed 5 cm. The project also stipulates that the construction of the bridge should begin a month after the construction of the embankment. After the computational analysis, it was shown that the required conditions are not met and it is necessary to improve the soil in the form of installation of stone columns. Their installation is considered to be the optimal solution for accelerating the consolidation process and reducing the total settlement in fine-grained soil. It is very important to dimension them correctly.
