Prediction of Shear Strength and Volume Change Behaviour Using Hyperbolic Model

Many empirical correlations have been obtained and used not only to predict the engineering behavior of soils, but also as a way to validate experimental values. Of the available mathematical correlations, hyperbolic model has been widely used by many researchers to establish the stress - strain, time — settlement, time — swelling and time - shrinkage characteristics of fine grained soils. In this investigation an attempt is made to re-examine the suitability of hyperbolic model for widely varying plasticity characteristics, initial moisture content and initial density. Using hyperbolic model few equations are proposed in this paper to predict the stress — strain behaviour, suction — water content and time — shrinkage behaviour of soil for any liquid limit, initial moisture content and density. The validity of the proposed equations has been attempted and found to be in good agreement with experimental values.
