Abstract
Existing norms regulate only design rules for swelling soils, but do not provide an opportunity to predict the further behavior of the substrate in the case of chemical contamination. In addition, the process of behavior of swelling soils after their chemical fixation and the stress-strain state (VAT) of the system "fixed base - foundation - construction" The stress-strain state of a soil massif contaminated with peracetic acid was estimated. Stresses appearing in the soil massif in the natural state are determined after acid enters it and after chemical fixation with sodium silicate. All the parameters of the stress-strain state of the soil massif are obtained under various physical and mechanical conditions. It was determined that after the work on silicate consolidation of the soil mass, contaminated with solutions of peracetic acid, the magnitude of deformations decreases 26.11-48.9%, and the stresses in the soil massif decrease 1.8-2.6 times.
