Numerical Problem of Thermo-Consolidation of Porous Media with Rheological Skeleton Depending on the Variable Ambient Temperature

Abstract

The study presents the results of the numerical calculations of the temperature impact on the two phase medium deformation described with the usage of Biot equations of consolidations with the rheological Kelvin-Voigt skeleton at the example of thermoconsolidation of flotation waste landfill “Żelazny Most” under influence of its dead weight, filtration and temperature gradient. 3D geometrical model of the landfill is based on the geometric measurements of the area and its neighbourhood. A starting point for the calculations was the calculated water table of the underground waters in the landfill area. The data referring to the effective parameters of the model were partially obtained via laboratory tests of the materials coming from the landfill. The rest of the data was taken from the literature related to the mediums with similar characteristics. The results of the stress state in the landfill allow to define the sensitivity of the model’s parameters in the temperature changes.
