Abstract
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.
