Assessment of flood-control dam stability in Yakutsk (Russia)

Abstract
The article presents the results of an investigation of the permafrost conditions of the embarkment dam in Yakutsk, which is located in the low floodplain of the Lena River. Dam site 3 rests on thawed soils represented by multi-grained water-saturated alluvial sands of various densities. The measured soil temperature alters from +6 to +6.4°C at a depth of 10 m. The high temperature was attributable to the discharge of warm water from the Combined heat and power (CHP) plant in Yakutsk into the enclosed cooling pond. Electrical resistivity tomography (ERT) is a highly effective geophysical method for delineating seepage zones in the earthen dam body, and determining the upper permafrost table at the base of construction. We have provided recommendations for the static and filtration stability of the study site.
