Abstract

Klimatske promjene rezultiraju ekstremnim vremenskim uvjetima, koje negativan utjecaj imaju i na željezničku infrastrukturu. U ovome je radu opisan utjecaj veoma visokih i niskih temperatura, snijega i leda, utjecaj obilnih oborina i poplava, jakog vjetra, snažnih i visokih valova generiranih jakim vjetrom na pruge u obalnom području. Nakon analize utjecaja vremenskih nepogoda na komponente željezničke infrastrukture, opisane su mjere koje se provode kako bi se željeznička infrastruktura zaštitila od vremenskih nepogoda. Opisane su mjere zaštite tračnica od izvijanja kod pojave visokih temperatura, primjena burobrana, opisane su mjere kojima se smanjuje utjecaj poplava na prugu, kao i načini sanacije klizišta i stabilizacije pokosa usjeka i nasipa, primjena grijača skretnica. Prikazani su načini uklanjanja snijega i leda s pruge. Također je objašnjeno i ventiliranje nasipa koje se primjenjuje na prugama izgrađenim na sloju zamrznutog tla.

Abstract (english)

Climate changes lead to extreme weather conditions, which also have a negative impact on the railway infrastructure. This paper describes the effects of very high and low temperatures, snow and ice, heavy precipitation and flooding, strong wind, strong and high waves generated by strong wind on railways in coastal areas. In addition, this paper describes measures to protect railway infrastructure from weather disasters. Measures to protect rails from buckling during high temperatures, the use of windbreaks, measures to reduce the impact of flooding on railway, ways to remediate landslides and stabilize cuts and embankments, and the use of turnout heaters are described. Methods for removing snow and ice from tracks are shown in this paper. Ventilation of embankments used on railways built on permafrost soils is also explained.
