Цель: Целью работы являлась оценка эффективности двух методов стабилизации балластной призмы железнодорожного пути: технологии послойного уплотнения балласта и армирования балластного слоя георешеткой. Методы: Для проведения исследований была создана модель балластной призмы, на которой проводились динамические испытания, имитирующие воздействие проходящего поезда. В ходе экспериментов измерялись осадки балластной призмы при использовании каждой из рассматриваемых технологий, а также в контрольном варианте без применения каких-либо дополнительных мер. Результаты: Результаты демонстрируют влияние каждой технологии на деформационные характеристики балластной призмы и позволяют оценить их эффективность в снижении осадок и повышении общей стабильности железнодорожного пути. В частности, показано, что применение георешетки и послойного уплотнения приводит к значительному уменьшению вертикальных деформаций по сравнению с неармированным балластом. Практическая значимость: Полученные выводы имеют важное значение для оптимизации конструктивных решений при строительстве и реконструкции железнодорожных путей и могут способствовать повышению их надежности и долговечности.

Purpose: To evaluate the effectiveness of two methods for stabilizing railway ballast: layer-by-layer ballast compaction technology and geogrid reinforcement of the ballast layer. Methods: The research was conducted using a ballast prism model, on which dynamic tests were performed in order to simulate the impact of a passing train. During the course of the experiments, the settlement of the ballast prism was measured applying each of the technologies under study. The control measurements without any reinforcement were performed as well. Results: The experiment results demonstrate the positive influence of the technologies under study on the deformation parameters of the ballast prism and allow for evaluating their effectiveness in reducing settlement and improving the overall stability of the railway track. The application of geogrids and layer-by-layer compaction has been shown to result in a significant reduction in vertical deformations compared to the ballast without reinforcement. Practical significance: The conclusions that are derived from this study will be of great importance when it comes to the optimization of design solutions in the construction and reconstruction of railway tracks. Furthermore, they can contribute to the improvement of their reliability and durability.
