Geotechnical Parameters of Landslide-Prone Laflamme Sea Deposits, Canada: Uncertainties and Correlations

Due to inherent variability arising from unpredictable geological depositional and post-depositional processes, the geotechnical parameters of Laflamme sea clay deposits remain highly uncertain. This study aims develop apply a methodology assess uncertainties using statistical distributions for landslide-prone Saguenay Lac-Saint-Jean (SLSJ) region. We used measured physical mechanical Sea clays various locations in SLSJ region characterize representative manner. Goodness-of-fit tests assign each parameter distribution function their descriptive analysis. found that quality these is significantly influenced by outliers. The detected outliers dataset considerably impact type specific parameter. Subsequently, appropriate functions were assigned after treating derived coefficient values high comparison literature with cone penetration test data being only exception. Finally, results indicated Saguenay-Lac-Saint-Jean marine are as compared Scandinavian relatively comparable other eastern Canadian clays.
