Действующие нормативные документы в части восстановления и усиления железобетонных конструкций не в полной мере соответствуют именно вопросам, связанным с результатами динамических воздействий, имеющих характерные особенности. Также объем опубликованных научных работ по данной тематике не является достаточным и подразумевает необходимость дальнейших исследований. Тем не менее к настоящему времени проведено определенное количество работ по восстановлению таких конструкций с последующими испытаниями и подтверждением необходимого уровня надежности. В статье рассмотрен опыт восстановления железобетонных конструкций пролетных строений мостов, получивших повреждения в результате динамического удара от автотранспорта – результаты дорожно-транспортных происшествий. Проведен анализ и рассмотрены характерные повреждения, а также наиболее целесообразные варианты восстановления конструкций. Основным рекомендованным вариантом усиления является усиление конструкций с применением внешнего армирования на основе композиционных материалов из углеволокна. Приведены результаты как расчетного обоснования, так и результаты статических испытаний в лабораторных условиях и реальных конструкций после восстановления.</p></abstract><trans-abstract xml:lang="en"><p>The problem of restoring reinforced concrete structures that have received dynamic impacts (emergency as a result of collisions with vehicles, damage as a result of dismantling nearby structures, explosive impacts) is quite an urgent issue. The current regulatory documents regarding the restoration and reinforcement of reinforced concrete structures do not fully correspond to the issues related to the results of dynamic impacts that have characteristic features. Also, the volume of published scientific papers on this topic is not sufficient and implies the need for further research. Nevertheless, to date, a certain amount of work has been carried out to restore such structures with subsequent tests and confirmation of the required level of reliability. The article considers the experience of restoring reinforced concrete structures of bridge spans that were damaged as a result of dynamic impact from vehicles - the result.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>восстановление</kwd><kwd>усиление</kwd><kwd>динамическое воздействие</kwd><kwd>внешнее армирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>restoration</kwd><kwd>reinforcement</kwd><kwd>dynamic impact</kwd><kwd>external reinforcement</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">Шилин А.А., Пшеничный В.А., Картузов Д.В.
