Abstract

Domestic and foreign research on the stability of seamless track plane frame have relatively mature achievement. And it can able to accurately calculate long rail temperature inside force under the condition of different parameters. But there are a few literature reported about under the condition of vertical settlement of track stability analysis. The paper study about under the condition of vertical settlement of track deformation analysis. Analysis of track displacement distribution and the law of development under the condition of embankment settlement diseases based on nonlinear finite element method. Research indicates that rail vertical displacement and roadbed subsidence has the linear relationship in the range of track bed resistance to be effective. When the roadbed arch and sink alternately that will be a significant increase in rail displacement.
