The aim of this study is the development of new structural and technological solutions in RCC dams in order to reduce the consumption of cement and expand their use on non-rock foundations, which will allow them to successfully compete with concrete face rockfill dams. The numerical analyses of static and seismic stress-strain state (SST) of gravitational dams in roller compacted very lean concrete dams have been made, as well as their stability, strength and cost have been assessed. For rock and dense sandy-gravel foundations the most economical is the concrete face rockfill dam and symmetrical RCC dam of very lean concrete with bases (0.5-0.7) of both slopes and outer zones of conventional concrete and central zone of rockfill strengthened by cement-ash mortar. Taking into account that the cost of diversion and spillway tunnels for very lean RCC dam will be less and the construction period - shorter than for the concrete face rockfill dam, it can be concluded that variant of symmetrical RCC dam of very lean concrete is the technically and economically effective. Symmetrical RCC dams of very lean concrete with 1V/(0.5-0.7)H slopes have more seismic resistance and technical and economic efficiency as compared with conventional gravitational RCC dams and other types of dams. These dams up to 200 m high can be built on rock foundations and up to 100 m high - on dense sandy gravel foundations.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">В последние 20 лет плотины из укатанного бетона (УБ) продолжают строить во многих странах ввиду их технико-экономических преимуществ по сравнению с обычными плотинами из вибрированного бетона и грунтовыми плотинами. Цель исследования - разработать новые конструктивно-технологические решения в плотинах из УБ с целью снижения расхода цемента и расширения их применения на нескальных основаниях, что позволит им успешно конкурировать с грунтовыми плотинами с экранами из железобетона. Выполнены численные расчеты статического и сейсмического напряженно-деформированного состояния гравитационных плотин из особо тощего укатанного бетона, а также оценка их устойчивости, прочности и стоимости. Наиболее экономичными для скального и плотного песчано-гравелистого оснований являются грунтовая плотина с экраном из железобетона и симметричная плотина с заложением откосов 0,5-0,7 с наружными зонами из особо тощего укатанного бетона и центральной зоной из камня, упрочненного цементно-зольным раствором. Учитывая, что стоимость отводящих и водосбросных туннелей при плотине из особо тощего укатанного бетона будет меньше, а срок строительства - короче, чем при грунтовой плотине с экраном из железобетона, можно сделать вывод о технико-экономической эффективности варианта плотины из особо тощего укатанного бетона. Плотины симметричного профиля из особо тощего укатанного бетона с заложением обоих откосов 0,5-0,7 обладают более высокой сейсмостойкостью и технико-экономической эффективностью по сравнению с обычными гравитационными плотинами из УБ и другими видами плотин. Плотины данного типа высотой до 200 м можно строить на скальных основаниях, а высотой до 100 м - на плотных песчано-гравелистых основаниях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>very lean roller compacted concrete</kwd><kwd>dams</kwd><kwd>strengthened by cement rockfill</kwd><kwd>geomembrane</kwd><kwd>stress-strain state</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>плотины</kwd><kwd>особо тощий укатанный бетон</kwd><kwd>упрочненный цементом камень</kwd><kwd>геомембрана</kwd><kwd>напряженно-деформированное состояние</kwd><kwd>сейсмостойкост</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">Londe P.
