Purpose. To develop analytical method for complex properties constructions calculations. To study viscoelasticity influence on construction stress-strain state and the possibility of considering final deformations.

Methodology. The mathematical model of tree-dimensional problem on load transfer from supporting element to the viscoelastic massif was constructed.

Findings. The circle of analytical solutions for nonlinear elasticity and linear viscoelasticity theory problems was extended by means of elaborating perturbation method.

Originality. The asymptotic method for three-dimensional linear viscoelasticity of orthotropic bodies problems solutions or for nonlinear problems was elaborated. Analytical solutions of new problems on load transfer through supporting element to the viscoelastic material massif in spatial statement were received.

Practical value. The method suggested allows passing from the solution of the complex mixed tasks of mechanics to the consecutive solution of potential theory problems, which is the most developed section of mathematical physics. The solutions of a range of new complex challenges received due to the offered approach provide an opportunity to analyse stress-strain state of bodies with supporting elements. These results can be used in engineering calculations of piles foundations and substructures.
