FIELD: construction.
SUBSTANCE: invention relates to construction of shallow buried foundations on a natural base, shallow buried pile caps of foundations and underground structures of normal level of responsibility in winter period on seasonally frost heaving soil beds. Method involves determination of the stress-strain state of the hard frozen soil and the foundation at their interaction in the process of freezing with vertical stresses in the soil from the structure.
EFFECT: technical result is providing operating reliability of the structure of the normal level of responsibility with minimum necessary requirements to material and power consumption of the structure and safe level of the building effect on the environment by determining a quantitative value of vertical impact stress of frost heave of the base soil on the structure along the whole area of the foundation supporting.
