Annotation: The article discusses the determination of uneven deformations of base caused by swelling of soil. An algorithm is proposed for determining additional vertical stresses at arbitrary points in the soil massif, taking into account the weight of the un moistened part of the soil mass beyond the soaking area. The results obtained by the proposed algorithm are compared using the finite element method and in accordance with the current regulatory documents. Analysis of the results has showed that the proposed algorithm more correctly takes into account the effect of the wetted parts of the soil mass located in the direction of the long side of the soaking area, compared to the tabulated dependencies. Simplified formulas are proposed for determining equivalent loads and forced displacements of the base when calculating structures interacting with swelling soil.
Keywords: expansive soils, non-uniform deformations of base, forced displacement, equivalent loads.
