Experience in the application of surface foundations for a frame building in the vicinity of St. Petersburg
The article presents the experience of constructing buildings on surface foundations in winter season. Within the frames of the investigation, there were evaluated temperatures in the base composed of heaving soils, as well as foundation displacements during the winter period. There have been were performed calculations of temperature fields and soil heaving deformation using the Termoground program. It is shown that despite the relatively big depth of the base soil freezing, the maximum displacements of the foundations did not exceed 7 mm, which is quite acceptable for a frame building.
