Maryna Oleksandrivna Snitsar

Abstract


Problems creep swelling soil when moistened with water T = 18 ÷ 20 ° C and high water temperature T = 40 ÷ 80 ° C or more.

By testing samples of swelling soils of montmorillonite and bentonite clays in the laboratory when moistened with water T = 18 ÷ 20 ° C and T = 40 ÷ 80 ° C or more different sealing pressure, simulating the pressure on family structures were obtained creep curves.

There were tested the possibility of using different theories of hereditary creep, such as the theory of aging, hereditary creep theory of linear, nonlinear creep theory.

It was found that the most best describes the family of creep curves swelling clay soils when wet with water T = 18 ÷ 20 ° C and T = 40 ÷ 80 ° C and a linear theory of hereditary creep Yu. N. Rabotnov with the nuclei of the power series of Abel.
