| Abstract: | A finite element model was established for lateral expansion and bending of jointless track, and corresponding formula was deduced and computation program was developed. The model was used for analysis of the impact of the following factors on track stability: track bed lateral resistance, sleeper failure, lateral elastic coefficient of fasteners, curve radius, and initial bending of track. Concrete measures for improving track stability were put forward. |
