The article considers the unique Rogun hydroelectric power station (HEPS), which is being built in difficult geological conditions and is burdened by the presence of a soluble rock salt layer at its base. The results of field studies of the hydro - and geochemical regime at the base of the dam are presented. The ranges of changes in the geotemperature field and the concentration of underground mineralized water are investigated and measured. A set of rational parameters of the water-soluble base monitoring system and requirements for the method and means of measuring the concentration of underground water are formulated.

В статье рассмотрена уникальная Рогунская ГЭС, возводимая в сложных геологических условиях и отягощённая наличием растворимого пласта каменной соли в ее основании. Приведены результатов натурных исследований гидро- и геохимического режима в основании плотины, исследованы и измерены диапазоны изменения геотемпературного поля и концентрации подземных минерализованных вод. Сформулирована совокупность рациональных параметров системы мониторинга водорастворимого основания и требования к методу и средству измерений концентрации подземных вод.
