Yield strength and critical strength of liquefiable sands in sloping ground Available to Purchase

Because undisturbed sampling of liquefiable sands is very difficult, if not impossible, and information on consolidation and ageing history of cohesionless soil deposits is not readily available for properly reconstituting laboratory specimens, there has been a considerable interest in correlating pre-liquefaction mobilised undrained shear strength, s_u(yield,mob), and post-liquefaction mobilised undrained shear strength, s_u(critical,mob), with measurements by in situ tests such as SPT and CPT. The s_u(yield,mob), which is overcome to trigger liquefaction, and s_u(critical,mob), which is available after liquefaction, are back-calculated by stability analysis of field liquefaction failures.
