Результаты экспериментов показали, что при углах падения менее 25° коэффициенты отражения от азимута практически не зависят. При бóльших углах падения наблюдается азимутальная зависимость коэффициентов отражения, наиболее сильно проявляющаяся при азимутах от 45° до 75°. Результаты измерений в направлении слоистости хорошо согласуются с теоретическими коэффициентами отражения для границы изотропных сред.</p></abstract><trans-abstract xml:lang="en"><p>The physical modelling of elastic waves reflected from the boundary between the water and the model of low-velocity azimuthally anisotropic medium was carried out. The model of anisotropic medium was made using 3D printer. The results of experiments showed that the reflection coefficients are practically independent from the azimuth at the angles of incidence less than 25°. At larger angles of incidence, the azimuthal dependence of the reflection coefficients is observed, which is most pronounced at azimuths from 45° to 75°. The results of measurements in the layering direction are in good agreement with the theoretical reflection coefficients for the boundary of isotropic media.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Азимутально-анизотропная среда</kwd><kwd>коэффициенты отражения</kwd><kwd>физическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Azimuthally anisotropic medium</kwd><kwd>reflection coefficients</kwd><kwd>physical modelling</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке проекта ФНИ № 0331-2019-0009 «Динамический анализ сейсмических данных для построения реалистичных моделей геологической среды на основе математического и физического моделирования»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Аки К., Ричардс П.
