AbstractThe paper presents values of coefficient of consolidation, Cv, of typical moraine sediments from the Mackenzie valley, NWT, Canada. Coefficient of consolidation is a key parameter for analysis of excess pore pressure and thaw consolidation settlement of fine grained soils in permafrost regions. Due to limited availability of tested values of this parameter, selection of Cv values for analysis of pore pressure and settlement during thawing and post thaw conditions is a difficult task for researchers and practitioners. In this paper, 20 soil samples from 8 landslide sites in the Mackenzie valley were collected and tested for coefficient of consolidation. The tested Cv values with other geotechnical index properties are presented to enrich crucial data for fine grained soils in the region.
