Evaluation of bulk earth structure on morainic foundation

The bulk earth hydrotechnical structures are considered from the standpoint of requirements mantained for important facilities. Complex georadar and seismic tomography studies were performed on the dam of the River Pirenga. The obtained research results were used to construct a geomechanic model and to carry out purposeful computer modeling. Performed works allowed to make estimation of the dam condition, to site depression plane, and to reveal local zones of high water saturation and filtration. The research results can be used as a methodological and scientific-engineering basis for substantiated prediction of the most sensitive areas (zones) of the earth bulk hydrotechnical facility erected on morainic foundation in conditions of Murmansk region and Northern Karelia.
