Исследования выполнены на железобетонных моделях фундаментов и металлическом штампе в песчаном лотке. Анализ затронул такие факторы работы системы «фундамент-грунт» при наличии быстрого догружения как изменение несущей способности фундамента на изгиб, осадка основания, трансформация эпюры нормальных контактных напряжений. Выявлены причины снижения несущей способности фундаментов на изгиб при быстром догружении, основной из которых является изменение формы эпюры нормальных контактных напряжений. Определены факторы, влияющие на концентрации нормальных контактных напряжений у краевых зон подошвы фундамента, среди которых: разная скорость протекания составляющих процесса перераспределения напряжений в основании, развитие дилатансии и др.</p></abstract><trans-abstract xml:lang="en"><p>The results of experimental studies of the force interaction of models of free-standing foundations with a sandy base under rapid additional loading are presented. The studies were carried out on reinforced concrete foundation models and a metal stamp in a sand tray. The analysis touched upon such factors of the operation of the “foundation-soil” system in the presence of rapid additional loading as a change in the bearing capacity of the foundation for bending, foundation settlement, transformation of the diagram of normal contact stresses. The reasons for the decrease in the bearing capacity of foundations for bending during rapid additional loading have been identified, the main one of which is a change in the shape of the diagram of normal contact stresses. Factors influencing the concentration of normal contact stresses near the edge zones of the foundation base have been identified, including: different rates of components of the stress redistribution process in the foundation, the development of dilation, etc.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>силовое взаимодействие фундаментов с основанием</kwd><kwd>осадка  фундаментов</kwd><kwd>нормальные контактные напряжения</kwd><kwd>деформации</kwd><kwd>отдельно стоящий  фундамент</kwd><kwd>прогрессирующее обрушение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Force interaction of foundations with soil</kwd><kwd>settlement of foundations</kwd><kwd>normal contact  stresses</kwd><kwd>deformations</kwd><kwd>free-standing foundation</kwd><kwd>progressive collapse</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Тер-Мартиросян, А.
