The purpose of the study is to control the state of the contact of the concrete dam foot with the foundation based on the analysis of a set of field studies of the vertical deformations of the near-contact zone of the foundation of the concrete dam sections and the total draft of the sections of the concrete dam to justify the stability of the concrete dam sections. In order to control the vertical deformations of the near-contact zone of the rock foundation, string control and measuring equipment (displacement sensors PLPS-10) was installed. The total draft of the concrete dam sections is measured by means of ceiling marks installed in the grout gallery. Analysis of the field data on total drafts of concrete dam sections and vertical deformations of the near-contact section of the rock foundation showed that the contact joint between the foot of the concrete dam sections and the foundation is in vertical compression. The results of the analysis of the available data of complex studies of vertical deformations of the near-contact layer of the rock foundation and the total draft of the concrete dam sections made it possible to substantiate the stability of the concrete dam sections.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Представлены результаты анализа данных комплексных натурных исследований вертикальных деформаций приконтактного слоя скального основания и полных осадок секций бетонной плотины Богучанской ГЭС в целях определения состояния контакта подошвы бетонной плотины со скальным основанием. Цель исследования заключается в контроле состояния контакта подошвы бетонной плотины с основанием посредством анализа комплекса натурных наблюдений за вертикальными деформациями приконтактной зоны основания секций бетонной плотины и полными осадками секций бетонной плотины для обоснования устойчивости секций бетонной плотины. В целях контроля вертикальных деформаций приконтактной зоны скального основания установлена струнная контрольно-измерительная аппаратура (датчики перемещений ПЛПС-10). Полные осадки секций бетонной плотины измеряются с помощью потолочных марок, установленных в цементационной галерее. Анализ натурных данных о полных осадках секций бетонной плотины и вертикальных деформациях приконтактного участка скального основания показал, что контактный шов между подошвой секций бетонной плотины и основанием находится в условиях вертикального сжатия. Результаты анализа имеющихся данных комплексных исследований вертикальных деформаций приконтактного слоя скального основания и полных осадок секций бетонной плотины позволили обосновать устойчивость секций бетонной плотины.</p></trans-abstract><kwd-group xml:lang="en"><kwd>concrete dam</kwd><kwd>rock foundation</kwd><kwd>near-contact zone</kwd><kwd>instrumentation</kwd><kwd>field observation data</kwd><kwd>total draft</kwd><kwd>vertical deformations</kwd><kwd>stability</kwd><kwd>concrete dam</kwd><kwd>sections</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бетонная плотина</kwd><kwd>скальное основание</kwd><kwd>приконтактная зона</kwd><kwd>контрольно-измерительные приборы</kwd><kwd>данные</kwd><kwd>натурные наблюдения</kwd><kwd>полные осадки</kwd><kwd>вертикальные деформации</kwd><kwd>устойчивость</kwd><kwd>секции</kwd><kwd>бетонная плотина</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">Kalustyan E.S.
