justify;">The compaction of the snow base of the wintering complex under construction of the Russian Antarctic station “Vostok” is considered, which was required due to the unsuitability of the natural snow base for the perception of loads from the supports of the foundation of the wintering complex. Technical solutions were developed for snow base compaction on the basis of heating by solar radiation with the use of thermal mat and on the basis of snow vacuuming. The computational justification of the developed technical solutions was performed, which was carried out based on spatial finite element models using the computational software complex ANSYS. In this case, to substantiate the method of snow base compaction by solar radiation heating with the use of thermal mat, the calculated volume was analyzed, including the snow base zone, thermal mat and the space filled with air. When substantiating the method of snow base compaction by snow vacuuming, there was explored the calculation area for modeling the method of vacuuming for the hermetic volume of the excavation pit with immersed columns under the wintering complex foundation supports. The results of the of the calculated research have fully confirmed the assumptions laid down in the technical solutions for compaction of the wintering complex snow base by using of thermal mat and snow vacuuming.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Рассмотрено уплотнение снежного основания строящегося зимовочного комплекса Российской антарктической станции «Восток», потребовавшееся по причине непригодности естественного снежного основания для восприятия нагрузок от опор фундамента зимовочного комплекса. Разработаны технические решения по уплотнению снежного основания на основе прогрева солнечной радиацией с применением термомата и на основе вакуумирования снега. Выполнено расчетное обоснование разработанных технических решений, проведенное на основе пространственных конечноэлементных моделей в рамках вычислительного программного комплекса ANSYS. Для обоснования способа уплотнения снежного основания нагревом солнечной радиацией с применением термомата проанализирован расчетный объем, включающий зону снежного основания, термомат и пространство, заполненное воздухом. При обосновании способа уплотнения снежного основания путем вакуумирования снега изучалась расчетная область для моделирования способа вакуумирования герметичного объема котлована с погруженными колоннами под опорами фундамента зимовочного комплекса. Результаты проведенных расчетных исследований полностью подтвердили предпосылки, заложенные в технических решениях по уплотнению снежного основания зимовочного комплекса на основе применения термомата и на основе применения вакуумирования снега.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Antarctic station “Vostok”</kwd><kwd>foundation supports</kwd><kwd>technical solutions</kwd><kwd>thermal mat</kwd><kwd>heating by solar radiation</kwd><kwd>snow vacuuming</kwd><kwd>calculation justification</kwd><kwd>finite elements models</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>антарктическая станция «Восток»</kwd><kwd>опоры фундамента</kwd><kwd>технические решения</kwd><kwd>термомат</kwd><kwd>нагрев солнечной радиацией</kwd><kwd>вакуумирование снега</kwd><kwd>расчетное обоснование</kwd><kwd>конечноэлементные модели</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">Puntus V.A., Myasepp K.K.
