Currently, there is an active development of large deposits located on the shelf and the northern rivers (Ob Bay, Yenisei), from where delivery to the places of consumption should be made. The most convenient type of transportation is the pipeline. Its route often crosses water areas, the size of which can reach five kilometres or more. Such dimensions allow the occurrence of a wave load acting on the pipeline. The issue of pipeline stability is especially relevant for designers in order to avoid accidents during operation. Nowadays, the regulatory documentation does not address this issue. Only the force of Archimedes is considered, without taking into account the wave action. The causes and process of moving the pipe up in the ground are difficult to theoretically analyze, therefore, it is mainly studied by empirical methods. In this work, the dependence between the wave load and the buoyancy force is established experimentally. The series of experiments was conducted with changing wave parameters and pipeline depth. This article will be useful for submarine pipeline designers.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Представлены результаты экспериментальных исследований по воздействию волновой нагрузки на заглубленный трубопровод. В настоящее время происходит активное освоение больших месторождений, расположенных на шельфе и северных реках (таких как Обская губа, Енисей), откуда должна производиться доставка к местам потребления. Наиболее удобным видом транспортировки жидких веществ является трубопровод. Чаще всего его трасса пересекает водные территории, размеры которых могут достигать пяти километров и более. Подобные габариты допускают возникновение волновой нагрузки, воздействующей на трубопровод. Вопрос его устойчивости особенно актуален для проектировщиков, чтобы избежать возникновения аварийных ситуаций в ходе эксплуатации. На сегодняшний день нормативная документация не рассматривает этот вопрос. Учитывается только сила Архимеда без волнового воздействия. Причины и процесс перемещения трубы в грунте вверх с большим трудом поддаются теоретическому анализу, поэтому в основном изучаются эмпирическими методами. В данной работе экспериментальным путем устанавливается зависимость между волновой нагрузкой и выталкивающей силой. Проводится серия экспериментов с меняющимися параметрами волны и заглубления трубопровода. Материалы исследования будут полезны проектировщикам подводных морских трубопроводов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>submarine pipeline</kwd><kwd>pipeline stability</kwd><kwd>experimental studies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>морской подводный трубопровод</kwd><kwd>устойчивость трубопровода</kwd><kwd>экспериментальные исследования</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Zhao E, Qu K, Mu L, Kraatz S, Shi B.
