ESTIMATION OF THE STRESS-DEFORMED STATE OF GROUND, POLLUTED BY PEROXIC ACID

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.

Проведена оценка напряженно-деформированного состояния массива грунта, загрязненного перуксусной кислотой. Определены напряжения, возникающие в массиве грунта в естественном состоянии, после попадания в него кислоты и химического закрепления его силикатом натрия. Получены все параметры напряженно-деформированного состояния грунтового массива при различных физико-механических условиях. Определено, что после проведения работ по закреплению силикатизацией грунтового массива, загрязненного растворами перуксусной кислоты, величина деформаций уменьшается на 26,11-48,9 %, а напряжения в грунтовом массиве снижаются в 1,8-2,6 раза.

 Проведено оцінку напружено-деформованого стану масиву ґрунту, забрудненого пероцтовою кислотою. Визначено напруги, що виникають у масиві ґрунту в природному стані, після потрапляння в нього кислоти і хімічного закріплення його силікатом натрію. Отримано всі параметри напружено-деформованого стану ґрунтового масиву при різних фізико-механічних умовах. Визначено, що після проведення робіт з закріплення силікатизацією ґрунтового масиву, забрудненого розчинами пероцтової кислоти, величина деформацій зменшується на 26,11-48,9 %, а напруги в ґрунтовому масиві знижуються в 1,8-2,6 разу.
