| Abstract: | Based on the established rheologic theoretical model, many cases are inquired from the rheologic point of view in this paper, including the longitudinal distribution of rail temperature force influenced by the temperature, the change of rail expansion value in the expansion region and the imperfection of lateral track, etc. It provids a basis for the further research on the rheologic theory of CWR track. |
