Use and Measurement of Fully Softened Shear Strength
The fully softened shear strength was defined by Skempton (1970) as the peak drained shear strength of a clay in a normally consolidated state. All the experience available on the applicability of the fully softened shear strength for slopes is based on back-analyses. Back-analyses of first-time …

Meaning, measurement, and field application of fully softened shear strength of stiff clays and clay shales
… for the reactivated landslides. Although fully softened shear strength mobilized in first-time slope failures has been recognized for decades, a comprehensive investigation on fully softened shear strength has not been made, which consists of its meaning, measurement, and field …

Drained shear strength of stiff clays for slope stability analyses
… better understanding of the drained residual and fully softened shear strengths of cohesive soils, the shear strength mobilized in field case histories involving previous and no previous sliding in stiff clays, and develop empirical relationships that describe the stress-dependent nature of the …

Analysis and behavior of preexisting landslides
… Empirical correlations for drained residual and fully softened friction angles are important in the back-analysis of landslides because they provide estimates for use in preliminary design and serve as a check for laboratory test and back-analysis results. The empirical correlations for drained …

Mechanisms of strength loss in stiff clays
… immediate reduction in shear strength to the fully softened value, and there is no lasting effect of consolidation by drying. After wetting the highly desiccated slopewash has the same strength as in the remolded, normally consolidated condition. Tests that simulated cyclic changes in normal …

Lime treatment to improve frictional resistance and stability of stiff clay slopes
… of changes in particle size and shape, and fully softened friction angle and residual friction angle, are used to examine possible mechanisms of lime-soil reactions. The main variables, in addition to soil mineralogy, are soil water content, lime content, and duration of lime-soil reactions. …
