Abstract: An analysis of the reasons for the displacements of long-term embankments maintained on permafrost soils indicates that they mainly occur due to plastic deformations in the layer of seasonal freezing and thawing; therefore, the reconstruction of permafrost is not effective in this case. It is proposed to strengthen these embankments with the help of using jet technology for cementation of the top layer of the roadbed. This approach is considered through the example of the deforming embankment on 6,278 km of the Turinskaya-Karymskaya section of the Trans-Siberian Railway.

Key words: embankment, permafrost roadbeds, temperature forecast, stress-strain state, jet technology
