Description: The Cam-clay model revised by SMP criterion (MCC-SMP) is implemented into a commercial software by using return mapping algorithm based on two-stage schemes, which includes elastic predictor and plastic corrector stages. The algorithm for updating the stress is provided. A subroutine for implementing the algorithm is developed. Numerical simulations of triaxial compression, triaxial tension and plane strain tests are performed. The precision of the algorithm is verified by comparing predicted values with experimental results. By using the MCC-SMP model, three-dimensional finite element analysis of consolidation behavior of trial embankment on soft soil, in Australia, is carried out. The changes in pore pressure, settlement and lateral displacement are analyzed and compared with the observed data in situ.
