Strength Selection for Static Slope Stability Analysis: On-Demand
Speakers: Christina J. Winckler, P.E., Senior Geotechnical Engineer, AECOM; and John W. France, P.E., D.GE, D.WRE, President, JWF Consulting, LLC
PDHs: This webinar is eligible for 2 PDH credits.
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, and methods for selection of strength parameters from field and laboratory data.
