Abstract: Abstract: The concept of residual strength has contributed greatly toward better understanding the magnitude of shearing resistance that is operative in overconsolidated clays and clay shales after large displacements have occurred. This residual shearing resistance is quite low in comparison to peak strengths determined by conventional laboratory procedures and equipment, and special apparatus and techniques capable of producing large displacements are required for the accurate laboratory determination of the residual shear strength. This report compares various laboratory procedures and equipment used for determining the residual strength of clay shales.
