Experimental and numerical modeling was conducted to analyze the temperature regime and the deformation state of a highway structure conceptualized as a geotechnical system comprising a “subgrade and the foundation of a highway made of frozen soil”. Potential disturbances of the temperature regime are considered, and a design and technological solution for thermal stabilization of the soil foundation under the subgrade in flooded areas using geocontainers is proposed. To study and evaluate the temperature regime of the highway structure, a series of laboratory experiments were performed. To account for the viscoelastic properties of the soil in the mathematical model of the soil foundation, time functions of the relative settlement of the soil foundation with geocontainers in the chosen temperature regime were obtained.
Keywords: temperature regime, highway, soil settlement, laboratory research, frozen viscoelastic soils.
