| Abstract: | This article discusses the current concepts of dam design and construction in permafrost regions. It is demonstrated that
embankment dams often change their state from frozen to thawed and back during the operation period. It is shown that
these transitions are not always attributable to observed climate warming. Where geotechnical, hydrogeological, and
permafrost conditions are complicated, proper performance of embankment dams can only be provided by adhering to a
selected thermal design for, as an example, a frozen state. |
