Abstract
This article is devoted to the study of the filtration coefficient depending on the loads applied to the material. In filtration theory, it is classical to solve problems with a constant filtration coefficient. Moreover, due to the conditionality of the filtration coefficient value by various physical and chemical processes, both in the solid fraction and in the liquid, its value is usually determined empirically. However, it is obvious that depending on the loads applied to the material, the pore space and filtration coefficient will change. This is especially true when using various filter materials, such as concrete. The latter, depending on the brand, can absorb the liquid quite well. Therefore, assuming that the pore space is a collection of capillary tubes, the paper shows the relationship between the filtration coefficient and the average pore diameter of the material. The dependence of the material filtration coefficient on the first invariant of the stress tensor arising in the medium is found. The change in the filtration coefficient of a concrete slab at different points is shown when a force load is applied to its upper surface.
