The Behaviour of Concrete Sleepers in Ballast

Original language description

The paper is focused on the behaviour of concrete sleepers in ballast. The sleeper vertical movements measurement and vibration acceleration evaluation caused by rolling stock is described in the first part. The typical behaviour of the sleeper ? ballastsystem is demonstrated, including the typical deflection curves of the sleepers. The differences for switch concrete sleepers are presented. The theoretical analysis of stresses in ballast under sleepers is described in the second part of the paper. Thhe static and dynamic analyses for selected types of sleepers were done by FEM. Principal differences have been found for stress distribution in ballast for wood and concrete sleepers. That is why the behaviour of concrete sleepers in ballast is distinctfrom wood sleepers. The different adverse effects are observed for these material types, especially in switches. Some defects or undesirable settlements of concrete sleepers can be explained based on the measurement and numerical solution
