It is considered a variant of the complete cohesion between the layers. The stress functions in each layer are written through the normal and tangential forces arising on the line of contact between the strip and the half-plane. The contact forces between the strip and the half-plane are determined from the system of two equations and conditions on the surface of the base. As a result, the stress functions in each layer are written through the surface load in the form of improper integrals. An analysis of the stress state is carried out according to the model of a three-layer iso- tropic base, depending on the elastic characteristics of the material of the layers. The influence of anisotropy of the material of layers in a three-layer soil mass is shown.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты расчетов на основе уравнений плоской задачи теории упругости по определению напряжений в трехслойном анизотропном основании под действием статической нормальной поверхностной нагрузки. Рассматривается вариант полного сцепления между слоями. Функции напряжений в каждом слое записываются через нормальные и касательные усилия, возникающие на линии контакта полосы и полуплоскости. Контактные усилия между полосой и полуплоскостью определяются из системы двух уравнений и условий на поверхности основания. В результате функции напряжений в каждом слое записываются через поверхностную нагрузку в виде несобственных интегралов. Проводится анализ напряженного состояния по модели трехслойного изотропно- го основания в зависимости от упругих характеристик материала слоев. Показано влияние анизотропии материала слоев в трехслойном грунтовом массиве.</p></trans-abstract><kwd-group xml:lang="en"><kwd>stress</kwd><kwd>anisotropy</kwd><kwd>elasticity</kwd><kwd>strip</kwd><kwd>half-plane</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>напряжение</kwd><kwd>анизотропия</kwd><kwd>упругость</kwd><kwd>полоса</kwd><kwd>полуплос- кость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
