Theoretical Examination Of The Longitudinal Behaviour Of Embedded Rails

Abstract

Abstract The longitudinal behaviour of embedded rails significantly differs from that of ballasted or slab tracks with direct rail fastenings. As the ambient temperature rises and falls, rails expand and contract, thereby imposing stress on the channel and embedding compound. In the article the author presents the creation of a method that makes the calculation and the inspection of embedded rails simpler and closer to the everyday engineering mentality. The design process includes an analysis of the displacement and normal forces along a rail axis.
