Abstract
Experimental and numerical modeling of the temperature regime and the deformed state of the highway structure, which is a geotechnical system of “subgrade and the foundation of the highway made of frozen soil”, was carried out. 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 is proposed. It implies the use of geocontainers. To study and evaluate the temperature regime of the highway structure, a series of laboratory experiments were carried out. To take into account the viscoelastic properties of the soil in the mathematical model of the soil foundation, time functions of the relative settling of the soil foundation with geocontainers in the chosen temperature regime were obtained.
