Effect Factors Analysis for the Lateral Stability of the Slab Track

Abstract:

Article Preview

In the paper, a mechanical model for the slab track was established. The mechanical characteristics and the deforming rule of slab track were analyzed using some parameters such as temperature load, the length and radius of circular curve, alignment irregularities, defects of fastening, etc. The results indicate that the lateral displacement of rails is periodically changed under the thermal force. The length and radius of circular curve has influence on the lateral displacement of rail. The lateral displacement of rails mainly influenced by resin’s elastic modulus, and has little relation with the length of circular curve. The mainly influence of resin’s elastic modulus is to the whole lateral displacement of track structure. alignment irregularities had a significant effect on the lateral displacement and track.
