Dams presently constructed of permafrost are divided into two basic types: thawed and frozen. Frozen dams exclude filtration. Frozen dams are created by means of a special artificial cooling system or are made in the course of constructing the cores by laminar freezing. The formation of an ice core is also possible, with natural freezing of a dam erected from thawed soil. There are many dams on the collective farms of Yakutiya that were frozen during the period of operation. In winters, the reservoirs formed by these dams are completely or partially drained, converting the dams into piles of earth during this period, surrounded on three sides by cold air. This report investigates the characteristics of the construction of all types of frozen dams. Draft trans. of mono. Opyt Stroitelstva Ployiny Merzlogo Tipa v Yakutii, Yakutsk, 1964 70p.
