THE FAILURE BEHAVIOUR OF OVER-CONSOLIDATED SOILS

An attempt has been made to separate strength into effective cohesion and friction components within the framework of Critical State Soil Mechanics under triaxial compression test conditions. The study accepts the validity of the Mohr-Coulomb relation as a tool to analyse the role of the components of strength. The uniqueness of the relation has been investigated and found to be test path dependent. The basic assumption made is that the observed compression is responsible for the cohesion component of strength. It has been established that at lower confining pressures and higher void ratios, cohesion is not significantly affected by the variation of confining pressures. The deduced relation can be applied to Cam and Weald clays and the relation reasonably described some general site data on cohesion and internal friction. (A)
