Abstract
We give the substantiation of the choice of methods and devices for physical laboratory modeling of the process of freezing and heaving of soils in order to study their heaving properties, as well as the parameters of the freezing process to verify the developed mathematical methods of the process modeling. The methods under consideration make it possible in freezing soils to set and control in automated mode the dynamics of the temperature state, the heat and water flows, the sheaving and shrinkage deformations, the moisture and density, the pore hydraulic pressure and the segregation ice release through the use of time-lapse video recording, the simulation of external mechanical and hydraulic loads.
