Stone columns are one of the most-used technologies of soil improvement in Slovakia. The stone columns installed using the vibro-replacement technology cause the change in the stress state and the properties of the surrounding soil. These changes are often not taken into account in the design. The paper deals with determine the change of the stress state and oedometer modulus in the soil around a single stone column. The calculations have been prepared in the form of a parametric study. The selected properties of ...
