FIELD: construction.
SUBSTANCE: base of a cylindrical reservoir consists of a layerwise compacted soil cushion reinforced with layers of geogrid/geotextile with rigid circular elements for their tensioning. The reinforced soil cushion comprises the upper part of permanent structural thickness and the lower part that has thickness that increases from the origin of the generatrix passing from the bottom of the reservoir wall at the angle of 28° to the horizontal line for sand soil and 40° for crushed stone, to the thickness of 3-6 m, which depends on base compressibility.
EFFECT: levelling vertical deformations of the reservoir bottom.
