The results of long-term geodetic studies during the formation of phosphogypsum dump of the Balakovo branch of Apatit JSC in the Saratov Region, which enabled studying the laws of development of deformation processes, caused by simultaneous manifestation of landslide displacements and subsidence of the dump surface, are presented. The reasons, mechanism, dynamics, and conditions of landslide formation on phosphogypsum dumps are considered, including the influence of the technogenic aquifer on bearing capacity of the structure base ground. The data of laboratory studies of phosphogypsum characterize it as highly compressible material with pronounced rheological properties, which predetermines the manifestation of large-scale and long-term subsidence deformations on phosphogypsum dumps. The information presented in the paper can be useful for assessing stability of phosphogypsum dumps and determining their maximum capacity.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты многолетних геодезических наблюдений при формировании отвала фосфогипса Балаковского филиала АО «Апатит» в Саратовской области, которые позволили изучить закономерности развития деформационных процессов, обусловленных одновременным проявлением оползневых смещений и осадок поверхности отвала. Рассмотрены причины, механизм, динамика и условия образования оползней на отвалах фосфогипса, включая влияние техногенного водоносного горизонта на изменение несущей способности основания сооружения. Данные лабораторных исследований фосфогипса характеризуют его как сильно сжимаемый материал, обладающий выраженными реологическими свойствами, что предопределяет проявление на отвалах фосфогипса больших по величине деформаций оседания, длительно не затухающих во времени. Представленные в статье сведения могут быть полезны при оценке устойчивости отвалов фосфогипса и определении их максимальной емкости.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отвалы фосфогипса</kwd><kwd>устойчивость откосов</kwd><kwd>деформационные процессы</kwd><kwd>осадки</kwd><kwd>оползни</kwd><kwd>механизм деформационных процессов</kwd><kwd>техногенный водоносный горизонт</kwd><kwd>деформационные свойства фосфогипса.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>phosphogypsum dumps</kwd><kwd>slope stability</kwd><kwd>deformation processes</kwd><kwd>subsidence</kwd><kwd>landslides</kwd><kwd>mechanism of deformation processes</kwd><kwd>technogenic aquifer</kwd><kwd>deformation properties of phosphogypsum</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">Гальперин А.М., Фёрстер В., Шеф Х.-Ю.
