Influence of Water Leaks on the Ground Temperature Regime beneath the Yakutsk Heat and Power Plant Buildings

Zabolotnik P.S.

 

This study examines the influence of hot process water leaks on ground temperatures beneath the buildings of the Yakutsk Combined Heat and Power Plant. The warming effect of leaks has been found to extend down to 15 m or more into the permafrost. At times, measurements detected a rise of ground temperatures up to 36°С. Water movement tends to concentrate in areas where the soils have already thawed due to previous leakage incidents. Even short leaks result in a significant increase in talik volume, while restoration of the frozen grounds will take many years.

 

Key words: permafrost, taliks, ground temperature, hot process water leaks.
