FIELD: construction. ^ SUBSTANCE: dam includes body erected from fine-grained material and transition layer made of consertal material and arranged in coastal abutments. Transition layer made of consertal material is arranged with addition of clay soil in amount that provides for the following content of pit-run fines in prepared soil mixture, and pit-run fines means fractions with conventional diameter of less than 5 mm, at least 40% and dust-clay fractions - at least 15% at continuous granulometry and 35% at discontinuous granulometry. ^ EFFECT: increased suffosion strength and filtration isotropy due to increased strength of transition layer. ^ 2 cl, 3 dwg |
