摘 要:The design of railway embankment with syntactical thermal insulator on permafrost soil is considered. It is shown that thermal insulator in embankment body allows one to save soils under embankment in frozen condition. It is recommended to put the thermal insulator nearly embankment foot in low embankments. The result of analytical calculation and mathematical modeling on the determination of the thermal insulator thickness are given.
