ABSTRACT
A five-element rheological model was applied for analysing the stress relaxation behaviour of silt clay loam soil. A triaxial test was conducted in order to determine the mechanical properties (Young's modulus and viscosity coefficient) of the soil. Mathematical analysis of the model was developed and analysed by the Finite Element Method (FEM). From the comparison of stress relaxation curves between an experimental and computed by FEM, it was found that the experimental time-dependent stress relaxation curve was in good agreement with the predicted one from the rheological model.
