Calculations of Thermal Stabilization of Transport Embankments and their Bases

During the construction of roads and railways in permafrost conditions methods of stabilization of soils using Thermosyphons have become very popular. In the design of such systems only an estimate of temperature field in the soil is carried out. At the same time it have been noted that the freezing of thawed soil is accompanied by the processes of frost heaving. There is a definite interest in the use of inclined and horizontal thermosyphons. In the article the examples of the calculations of changes of temperature fields and the stress-strain state of the embankment and its base in the annual cycle with the use of inclined thermosyphons are presented. The known program «Termoground» developed with the participation of the authors was used for the calculations. It is suggested that in the design of thermal stabilization of soil the calculations only of change of temperature fields in the soil are insufficient. It is also necessary the forecast of the deformations of heaving and thawing.
