Среди таких специальных нагрузок, учет которых обязателен при расчете объектов инфраструктуры высокоскоростных железнодорожных магистралей, выделяется нагрузка от аэродинамического воздействия движущегося высокоскоростного подвижного состава. Одной из наиболее подверженных аэродинамическому воздействию конструкций является пешеходный путепровод, что обуславливается его относительно небольшой массой и непосредственной близостью к движущемуся поезду. Выполненный анализ отечественных и зарубежных нормативов и методик учета аэродинамического воздействия от движущегося высокоскоростного поезда показал, что в них отсутствует ряд расчетных случаев, характерных для пешеходных переходов, автодорожных путепроводов, конкорсов и т. д., а именно воздействие на вертикальные поверхности, расположенные над габаритом перпендикулярно оси движения поезда.В данной работе рассматривается исследование аэродинамического воздействия высокоскоростного поезда на пешеходный путепровод. Анализ результатов выполненной серии расчетов позволил установить характер распределения давлений на поверхности рассматриваемого сооружения, в том числе и на фронтальную поверхность. Также были определены характер и интенсивность силового воздействия на конструкцию, а именно продольной и подъемной аэродинамических сил, в зависимости от положения движущегося поезда и таких параметров конструкции, как высота над уровнем головки рельса и расстояние от рассматриваемого сечения до оси движения поезда.В заключение приведены предложения по совершенствованию существующих методик учета аэродинамического воздействия.</p></abstract><trans-abstract xml:lang="en"><p>The design and construction of high-speed railways is accompanied by the need to consider certain loads and impacts that are not considered, as a rule, when designing conventional railways. It is one of such special loads, the consideration of which is mandatory when calculating infrastructure facilities of high-speed railways is the load from the aerodynamic impact of moving high-speed rolling stock One of the structures most susceptible to aerodynamic effects are pedestrian overpasses, which is due to their relatively small mass and proximity to a moving train. Performed analysis of domestic and foreign standards and the methods of accounting for the aerodynamic impact from a moving high-speed train showed that they lack a few calculated cases characteristic of pedestrian crossings, road overpasses, concourses, etc., namely, the impact on vertical surfaces located above the dimension perpendicular to the axis of movement of the train.This paper examines the study of the aerodynamic effect of a high-speed train on a pedestrian overpass. Analysis of the results of the performed series of calculations made it possible to establish the nature of the pressure distribution on the surface of the structure under consideration, including on the frontal surface. The nature and intensity of the force impact on the structure, namely the longitudinal one, was also determined and lifting aerodynamic forces, depending on the position of the moving train and design parameters such as the height above the level of the rail head and the distance from the section under consideration to the axis of movement of the train.In conclusion, proposals are made to improve the existing methods of accounting for aerodynamic effects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аэродинамика</kwd><kwd>высокоскоростная магистраль</kwd><kwd>ВСМ</kwd><kwd>мост</kwd><kwd>путепровод</kwd><kwd>конкорс</kwd><kwd>пешеходный переход</kwd><kwd>численное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aerodynamics</kwd><kwd>high-speed highway</kwd><kwd>HSR</kwd><kwd>bridge</kwd><kwd>overpass</kwd><kwd>concourse</kwd><kwd>pedestrian crossing</kwd><kwd>numerical simulation</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">Смирнов В.
