Field Research of the Heaving Pressure Occurring at Frost Penetration in the Soil under the Foundation Bed

Abstract

This article describes the results of field experimental studies of the heaving pressure development during freezing of the soil under the foundation bed. Due to the intensive development of areas North and North-East of Russia, studies on the impact of heaving soils on foundations and underground structures are currently assuming a special significance. The research that we carried out allowed us to reveal features of the heaving pressure development of clay soils during freezing under the foundation bed depending on conditions of freezing. We found that pressure formation depends largely on the location of the frozen area and the compressibility of the melt zone of the freezing soil. In the article, we propose measures to reduce the impact of heaving pressure on the foundation bed.
