The problem of interaction between ground anchor and surrounding soil under pressure grouting is solved by analytical method. This estimation makes it possible to calculate stresses at the interface between anchor and soil, which can be used for determination of anchor's bearing capacity. The problem consists of two stages: stresses in the surrounding soil are determined using prescribed displacements, and after that residual stresses are calculated on the basis of viscoelastic equation.
