Для этого требуется подготовка линий, поскольку движение тяжеловесных поездов по земляному полотну, спроектированному в конце XIX - начале XХ в. совсем для других нагрузок, может вызвать возникновение деформаций пути. В рамках испытаний, проводимых на участке Ковдор - Мурманск Октябрьской железной дороги в 2014-2016 гг., был апробирован и применен метод численного расчета параметров длинных неровностей, получаемых по данным путеизмерителей, позволяющий производить мониторинг участков с нестабильным земляным полотном без применения трудоемких геодезических работ.</p></abstract><trans-abstract xml:lang="en"><p>The work of the railway track in the conditions of operating cars with increased axial loads was constantly in the sphere of attention of domestic scientists. The increase in the carrying capacity of the railway network entails an increase in the axle loads and masses of trains. This requires upgrade of railway lines, because the traffic of heavy haul trains is carried out on the subgrade designed in the end of XIX - beginning of the XX century for quite other loads that can cause a deformation of track. In 2014-2016 complex tests of cars with an axial load of 27 tons were carried out by the task of the JSC “RZD” on the Kovdor - Murmansk section of the Oktyabrskaya Railway. During 2016 (spring and autumn) a geodetic survey of the pilot site was performed, the information obtained was compared with the results of a numerical calculation. In view of the complexity of geodetic work, a method of numeric calculating the parameters of extended irregularities using Fourier transforms, obtained from track data, was appraised in the tests, which makes it possible to monitor sections with an unstable subgrade without using complex geodetic work. This method has shown that the information obtained in geodetic work (leveling) and the transformed data of the track measuring car are well correlated. The obtained data on the calculation of the parameters of extended irregularities indicate the depression of the subgrade, showing that it is necessary to examine in detail the areas where cars with increased axial loads are to be put into circulation, as well as the areas of handling of heavy haul trains in satisfactory and unsatisfactory condition based on integrated assessment of track condition. The process of track deformation, recorded during the tests, is confirmed by the data of the world experience of heavy haul traffic. Application of the method of numerical analysis of the parameters of extended irregularities with the help of the Fourier transform allows identifying places with significant changes in the parameters of extended irregularities in the analyzed period.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>длинные неровности в профиле</kwd><kwd>натурные неровности</kwd><kwd>параметры длинных неровностей</kwd><kwd>деформация</kwd><kwd>тяжеловесное движение</kwd><kwd>повышенные осевые нагрузки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>extended irregularitites in rail profile</kwd><kwd>full-scale irregularitites</kwd><kwd>parameters of extended irregularities</kwd><kwd>deformation</kwd><kwd>heavy haul traffic</kwd><kwd>increased axial loads</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">Инфраструктура в условиях применения вагонов с повышенными осевыми нагрузками / В.
