ABSTRACT

Frost heaving of soils is a very common phenomenon typical for many regions of the world. In the last decade, new solutions have been introduced into construction practice. Shallow Foundations (SF) and Surface Foundations (SuF) are gaining popularity in the field of low-rise construction. For buildings with a deep underground part, “slurry wall” is often used as an external enclosing structure. In the instances noted, in the North, base freezing in SFs and SuFs is allowed, and soil in contact with vertical planes of trench walls freezes if pit opening is conducted in winter. In those cases, it is often necessary to take into account deformations caused by frost heaving and evaluate forces affecting structures. To estimate the effect of frost heaving on structures, it is required to have information on main characteristics of this phenomenon. Those are, first of all, deformations representing the source of heaving forces (tangential and normal). The article proposes to determine all parameters of frost heaving, including normal forces, by calculation.
