Analytical determination of the relaxation function of viscoelastic frozen soil based on experimental data

Abstract

Strength and creep of frozen soils are among the main mechanical properties for time estimation in the design of construction objects. Based on experimental data, the authors determined deformational mechanical characteristics of frozen soil, including creep, and obtained a creep function of frozen soil. Using this creep function, the authors analytically determined the relaxation function of frozen soil using the broken lines method. This methodology can be used in the design of foundations for construction objects made of frozen soils.
