  The paper describes a calculation method of residual deformation of embankment subjected to cyclic loading due to running trains. In the proposed method, characteristics of accumulated deformation were evaluated by the results of the cyclic loading triaxial tests, then the accumulated damage theory and linear elastic analysis by finite element method were conducted in each soil category to calculate the residual deformation of embankment due to the running trains. By the proposed method, an actual residual deformation of embankment due to the running trains can be evaluated quantitatively.
