Выполнен компьютерный эксперимент с помощью средств численного моделирования воздействия штормовых волн на берегозащитные сооружения и конструкции железнодорожного пути в районах интенсивного воздействия прибрежных штормовых приливов. Оценены интенсивность воздействия гидродинамических факторов на элементы конструкций и косвенное влияние традиционных берегозащитных сооружений на эрозию берега. Проведено компьютерное моделирование методом гидродинамики сглаженных частиц.</p><p>Построена карта распределения скоростей потока и избыточного давления для набегающей и отраженной волны на примере участка берега, получены численные показатели влияния гидродинамических факторов на береговые сооружения железнодорожного пути. Исследование показало преимущества интеграции указанных сооружений в естественный ландшафт благодаря значительному снижению воздействия отраженных волн на эрозию берега. Осуществлен сравнительный анализ влияния указанных гидродинамических факторов на классическую и альтернативную конструкции нижнего строения пути в прибрежной зоне, обеспечивающую максимальное использование естественной защиты береговой линии.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of the surrounding coastal relief of the North Caucasus Railway section, which is promising in terms of high-speed traffic development, and the coastal protection structures traditionally used on this section was carried out, and a three-dimensional map of the sailing directions near the section under study was constructed. A computer experiment was carried out using numerical modeling tools to examine the impact of storm waves on coastal protection structures and railway track structures in areas of intense coastal storm tide impact.</p><p>The intensity of the impact of hydrodynamic factors on structural elements and the indirect impact of traditional coastal protection structures on coastal erosion were estimated. Computer modeling was carried out using the smoothed particle hydrodynamics method.</p><p>A map of the distribution of flow velocities and excess pressure for the incident and reflected wave was constructed using a section of the coast as an example, and numerical indicators of the impact of hydrodynamic factors on the coastal structures of the railway were obtained. The study showed the advantages of integrating these structures into the natural landscape due to a significant reduction in the impact of reflected waves on coastal erosion. A comparative analysis of the impact of the specified hydrodynamic factors on the classical and alternative designs of the substructure of the track in the coastal zone, ensuring maximum use of the natural protection of the coastline, was carried out.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гидродинамика сглаженных частиц</kwd><kwd>подпорно-волноотбойные стены</kwd><kwd>железнодорожные сооружения</kwd><kwd>нижнее строение пути</kwd><kwd>эстакада</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrodynamics of smoothed particles</kwd><kwd>retaining and seawalls</kwd><kwd>railway structures</kwd><kwd>substructure of the track</kwd><kwd>overpass</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования, выполняемые по данной тематике, проводились в рамках реализации федеральной программы поддержки университетов «Приоритет-2030».</funding-statement><funding-statement xml:lang="en">The research carried out on this topic was conducted within the framework of the implementation of the federal program of support for universities “Priority-2030”.</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">Серебряков Г.Б., Гришин Н.А.
