摘      要：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 *** is proposed to strengthen these embankments with the help of using jet technology for cementation of the top layer of the *** approach is considered through the example of the deforming embankment on 6,278 km of the Turinskaya-Karymskaya section of the Trans-Siberian Railway.
