Abstract
The article presents a methodology for studying of the strength properties of frozen soils using a modernized automated testing complex (AIC "ASIS") produced by NPP "Geotek" LLC (Penza, Russia) and determining the dependence of the amount of unfrozen water in the soil on the temperature using an adiabatic calorimeter. On the samples of mudstone-like clay, it was found that the conditionally instantaneous strength of frozen soils depends non-linearly on the temperature and salt presence in pore solution. The dependences of the conditional instantaneous strength of mudstone – like clay samples on the amount of unfrozen water in these samples are studied. It is established that the strength properties of clay soils at negative temperatures are mainly determined by the total amount of unfrozen water. The genesis of unfrozen water (temperature or the combined effect of temperature and salt concentration in the pore solution) does not matter.
