Abstract
Summary
The influence of the glacial masses of the Quaternary glaciations on the structure and the physical properties of the upper part of the ground layer, which serves as the basis for the offshore structures and linear infrastructure facilities of the offshore oil fields on the shelf of the South-Eastern Baltic, is considered. The complex of hydrographic and geophysical works performed at the first stages of engineering surveys allows to evaluate various factors of the dynamic impact of continental glaciers on the formation of the surface of strong bearing soils, as well as weakened zones due to glacio-isostatic deformations and the accumulation of weak in strength relation soils in glacial lakes and channels.
