Experimetal measurement of soil-prestressed foundation interaction

Abstract

Several experimental measurements of reinforced concrete slab – subsoil interaction are compared with numerical analysis of shallow foundation by means of FEM. At the Faculty of Civil Engineering VSB – Technical University of Ostrava testing device was constructed so that the phenomena of soil – foundation interaction could be experimentally investigated and compared with numerical models. The experimental model was designed as a cutout of prestressed foundation slab-on-ground and the static load test was conceived as a simulation of local loading of a square shape column. During the static load test, measurements focused on observation of horizontal deformations, tension inside the slab and on the contact surface between foundation structure and subsoil. The described static load test was part of a series of experiments realized at the Faculty of Civil Engineering, VSB –Technical university of Ostrava.
