Abstract
Are investigated results obtained during supervision over change of hydraulic pressure and soil’s deformation while shielding inclined tunnel with hydro-surcharge on the breast for Saint Petersburg underground station «Admiralteiskaya». Are defined characteristics of anthropogenic hydro geological structure generated while shielding glacial soils. Is offered methodology for estimation soil deformation taking into account anthropogenic cracks of stratification and compaction – decompaction processes of clay breeds while changing hydraulic pressures. Is presented an example of estimation deformations of soils influenced by shielding.
