Physical and Mathematical simulation of Frozen soil Embankments

Abstract

One of the problems of natural resource development in Siberia is the absence of the advanced network of railway and automobile roads. Rocks unsuitable for the embankment construction almost over the whole region pose the problem of their transformation into suitable. The transport facility construction within the complicated Siberian conditions has accumulated the experience for the past two decades and expanded the list of local materials used in the structures, such as frozen clayey and peat soils. The durability and reliability of this soil mass depend upon its thermal conditions and stress-strain state. The suggested model takes into account the interaction between temperature field, moisture distribution, iceness, strain, and stress. The temperature and moisture have an effect on the stress-strain state of soil which, in turn, modifies the physical parameters of moisture and temperature field. This complicates the mathematical solution of the problem, but approximates it to the real behavior of embankments in Siberian conditions.
