Abstract
Slab track systems are in use for more than a hundred years, first as metro and tunnel systems, and today as a standard solution for track systems in urban surroundings and a solution for high-speed lines. The following slab track systems are used: systems with punctual fastening of the rail on sleepers incorporated in structure, systems with punctual fastening of the rail on sleepers laid and anchored on a supporting structure, systems with punctual or continual fastening of the rail without sleepers. The mutual characteristics of all types of standardized slab track systems are a high construction price, negligible maintenance costs and long service life compared to the track in ballast. The aim of this paper is to present slab track types.
Konstrukcije koloseka na čvrstoj podlozi primenjuju se vise od stotinu godina, najpre u metroima i tunelima, a danas kao standardno rešenje u urbanom okruženju i kao jedno od rešenja na prugama za velike brzine. U upotrebi su sledeći sistemi konstrukcija koloseka na čvrstoj podlozi: monolitni sistemi sa pragovima na betonskoj ploči sa diskretnim oslanjajem šina, sistemi sa diskretno oslonjenim šinama na betonske pragove položene na čvrstu podlogu, sistemi bez pragova sa diskretnim ili kontinualnim šinskim pričvršćenjem. Zajednička karakteristika svih standardnih tipova koloseka na čvrstoj podlozi je velika cena konstrukcije, neznatni troškovi održavanja i dug vek trajanja u odnosu na konstrukciju koloseka u zastoru od tucanika. Cilj ovog rada je predstavljanje i sistematizacija tipova konstrukcije koloseka na čvrstoj podlozi.
