Strength Recovery from Residual-State of Shear on Soils
Abstract Residual shear strength is used for design and repairs on slopes containing pre-existing shear surface. Some recent research suggested that the pre-existing shear surface of landslides can gain strength with time. In this study, torsional ring shear strength recovery tests on different soils using rest periods of up to 30 days are performed at the effective normal stress of 100 kN/m2. Test results show that recovered strength measured in the laboratory is slightly noticeable after a rest period of 3 days, but recovered strength is lost after a very small shear displacement. This paper mainly focuses on the strength recovery phenomenon from the residual-state of shear on different soils based on torsional ring shear test results and the mechanisms behind it.
