UIC recommendations for design of railway bridges

Abstract

This paper discusses the basic principles of interaction track/bridge. Influences of different bridge structures on the bridge expansion length were analyzed in order to avoid expansion joints in CWR track. Influences of track and bridge superstructure, as well as bridge support stiffness on the mentioned interaction were considered. In addition, performance requirements for rail fastening systems and longitudinal track restraint on bridge were considered. UIC (International Union of Railways) recommendations for design of railway bridges were presented. The aim of this paper is providing the basis for improvement of the existing technical regulations in the field of railway infrastructure, as well as its harmonisation with EU regulations.

Ovaj rad razmatra osnovne principe interakcije kolosek/most. Analizirani su uticaji različitih konstrukcija mostova na dilatacionu dužinu mosta kako bi se izbegla dilataciona sprava u koloseku sa kontinualno zavarenim šinama. Razmatrani su uticaji gornjeg stroja mosta kao i krutosti oslonaca mosta na pomenutu interakciju. Takođe, razmatrani su tehnički zahtevi za sisteme šinskih pričvršćenja i podužni otpor koloseka na mostu. Predstavljene su UIC (Međunarodna železnička unija) preporuke za projektovanje železničkih mostova. Cilj rada je stvaranje osnove za unapređenje postojeće tehničke regulative u oblasti železničke infrastrukture i njena harmonizacija sa EU regulativom.
