Abstract

The artificial ground freezing can be a highly potential, reliable and environmental friendly alternative to grouting for water-proof and reinforcement under difficult geologic conditions. After freezing, the pore water is converted to the ice phase and acts as a boding agent to increase the strength of frozen soil. Therefore, an additional tensile strength should be considered when dealing with frozen soils. However, a suitable constitutive model to describe the stress-strain relationship considering the tensile strength because the freezing phenomenon is not fully addressed yet. In the present laboratory experiment, a series of frozen soil triaxial tests was conducted. The soil samples were artificially frozen in various freezing temperatures and tested under different confining pressures. Also, in this paper, the novel constitutive model that can take into account the temperature effect on the stress-strain relationship is proposed. The proposed model is validated by the frozen soil triaxial tests results.
