The foundation is represented by a poroelastic layer saturated with gas-liquid mixture, a heterogeneous layer with a viscoelastic coating, and a heterogeneous layer with a subsurface liquid sheet. The foundation of the pack of layers is hard. The operation of the surface oscillator is represented as Fourier series, and the problem of steady-state oscillatory conditions is solved. Applying the Fourier integral transform to the equations that describe continuous media under satisfying boundary conditions allows the construction of integral formulas describing the stress-strain condition in the layer package. A numerical algorithm to study the dependence of the ground-wave propagation on the mechanical and geometrical characteristics of the problem is proposed. The models described are widely used in Geophysics, seismic exploration, construction, railway design, and new material designing.</p></abstract><trans-abstract xml:lang="ru"><p>Целью работы является изучение новых математических моделей, включающих в себя генератор колебаний и полуограниченное неоднородное по глубине основание, обладающее пористостью, флюидонасыщенностью, вязкоупругостью. В качестве основания рассмотрены пористоупругий слой, насыщенный смесью жидкости и газа, гетерогенный слой с вязкоупругим покрытием, гетерогенный слой с заглубленным жидким слоем. Основание пакета слоев - жесткое. Действие поверхностного осциллятора представляется в виде ряда Фурье и решается задача с установившимся режимом колебаний. Применение интегрального преобразования Фурье к уравнениям, описывающим сплошные среды, при удовлетворении граничным условиям позволило построить интегральные формулы, описывающие напряженно-деформированное состояние в пакете слоев. Предложен численный алгоритм для изучения зависимости распространения поверхностных волн от механических и геометрических характеристик задачи. Описанные модели широко применяются в геофизике, сейсморазведке, строительстве, проектировании железнодорожных магистралей, конструировании новых материалов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гетерогенная слоистая среда</kwd><kwd>волновое поле</kwd><kwd>распространение колебаний</kwd><kwd>заглубленный жидкий слой</kwd><kwd>heterogeneous layered medium</kwd><kwd>wave field</kwd><kwd>propagation of vibrations</kwd><kwd>embedded liquid layer</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Горшков, А.
