摘要

Characteristic specific features of the thermal regime of the "dam - bed" system are examined.rnThe northern construction-climatic zone (NCCZ) is characterized by severe climatic, complex geologic-engineering, and geocryologic conditions:rn1. winters with air temperatures to -60 - 70℃, short summers with maximum temperatures of 30-40℃, and mean annual air temperatures to -8 - 14℃;rn2. existence of continuous or insular frost, through or closed taliks, and temperature stratification; and,rn3. frozen soils and fissured rock, as a rule, possessing thermally induced slump-type-settlement properties, a sharp reduction in bearing capacity, and high permeability after thawing.
