Abstract
Understanding of a load redistribution into subsoil below building foundation is an importantknowledge for reliable design and its economy too. The article presents the results of a physical model of afoundation slab and its interaction with the subsoil. The interactions were investigated comprehensively bymonitoring the developments of stress in the subsoil and foundation slab settlement during its loading. Theload acting on the foundation was applied by strutting the hydraulic press against heavy steel frame whichwas established by the Department of Building Structures, Faculty of Civil Engineering of VSB -TU Ostravafor this purpose. The preparatory phase of the present experiment involved the homogenization of soil duringwhich trio pressure cells in three horizons were gradually fitted. The quality of homogenization was checkedon an ongoing basis through field tests: dynamic penetration load test, dynamic plate load test and seismicmeasurement of foundation slab response. Finally, the homogenized soil was subjected to mechanicalanalysis to determine the strength and deformation parameters for basic Mohr-Coulomb constitutive model.
