摘要 The main reasons for a breach of trouble-free operation of the subgrade are the different kinds of deformation, such as Wain load impact on subgrade surface, loss of stability to subgrade slope, weight of embankment on the base, and partial or complete failure of the railway track due to frost heaving. This paper gives a summary of deformation analysis methods being developed in Russia to estimate the operaling con- ditions of the railway subgrade.
