FIELD: construction.
SUBSTANCE: earth dam comprises a body, a base with an upper layer of ice-saturated soil, drainage slots and tubular drains. Drainage slots are made for the depth of the upper layer of ice-saturated soil of the base upstream the upper and lower slope of the body. A tubular drain is laid onto the bottom of the last slot.
EFFECT: efficient drainage of a thawing frozen base of a dam in process of construction of an earth dam in permafrost area.
