Abstract
U ovom radu su analizirana djelovanja potresnog opterećenja na pojedine dijelove kolosiječne konstrukcije s naglaskom na zastornu prizmu. Zastorna prizma je dio kolosiječne konstrukcije čija je uloga prije opterećenja od tračnica i pragova u dublje slojeve kolosiječne konstrukcije, a i načinjena je od nasutog, kompaktnog materijala. Zastorna prizma u velikoj je mjeri podložna oštećenjima od potresa. U ovom radu su za opis oštećenja zastorne prizme korišteni rezultati ispitivanja potresnog stola i simulacije potresa na kolosiječnu konstrukciju pomoću diskretne metode elemenata. Tijekovi i vrijednosti dobivene ispitivanjima su detaljno analizirani. Na temelju spoznaja o ponašanju i deformacijama zastorne prizme uslijed potresa analizirane su načini i postupci kod sanacija zastorne prizme nakon oštećenja uzrokovanih potresom. Postupci sanacije oštećenja elemenata donjeg i gornjeg ustroja. Zaključno su u radu navedena ključna svojstva zastorne prizme za njeno ponašanje kod potresa, moguća pojava deformacija i načini saniranja zastorne prizme.
Abstract (english)
In this paper, the effects of seismic load on individual parts of the track structure with emphasis on ballast are analysed. Ballast is a part of the track structure whose role is to transfer the load from the rails and sleepers to the substructure. Ballast is made of bulk, compact material and it is largely susceptible to earthquake damage. In this paper, the results of seismic table testing and earthquake simulation on a track structure using the discrete element method were used to describe the damage to the ballast. The flows and values obtained by the tests were analysed in detail. Based on the knowledge about the behaviour and deformations of ballast due to earthquakes, the methods and procedures for repairing the curtain prism after damage caused by earthquakes are analysed. Remediation procedures are described for damage to the elements of the lower and upper structure. In conclusion, the paper presents the key properties of ballast for its seismic behaviour, the possible occurrence of deformations and ways to ballast repair.
