Przemieszczenia pali iniekcyjnych w warunkach obciążenia osiowego

The results of relocation measurements carried out for injection piles under axial load in wide range of loads, considerably exceeding their normative carrying capacity, indicate that employed computational models do not represent actual deformation process in an appropriate way. Taking into account slide at the contact between pile side surface and soil makes it possible to approximate theoretical model behaviour to actual soil reaction. Moreover, the proposed model gives an opportunity to characterise many effects resulting from susceptible combination of two different materials - cement grout and soil. In particular when we abandon the assumption made in this work of the interaction between soil and pile deformation.
