Strength Selection for Static Slope Stability Analysis: On-Demand
This webinar will provide practical guidance on the selection of soil shear strength parameters for static slope stability analysis. Topics covered include: stress-strain behaviors of cohesionless and cohesive soils and their relationships to strength selection; drained and undrained strengths and their application in stability analysis; the differences between effective stress and total stress analysis methods; loading cases for stability analysis and appropriate strength selection for each case; methods for selection of strength parameters from field and laboratory data.
