EFFECTIVE SHEAR STRENGTH PARAMETERS FOR STIFF FISSURED CLAYS
Shear box and triaxial tests have been used to investigate the effective shear strength of a stiff fissured clay of constant mineralogy but variable plasticity. Different residual shearing mechanisms were recognised in the shear box tests with significantly different values of residual strength. The fully softened strength parameters appropriate for the analysis of first-time slides were investigated by both triaxial and shear box tests. The lower plasticity samples had a higher strength than the higher plasticity samples. For the soil tested both the residual and fully softened effective friction angles showed a pattern of dependence on the plasticity. It may be possible to establish similar correlations for other soils if the results reflect different shearing mechanisms caused by grading variations within a soil of constant clay mineralogy.
