The strength criterion is used to analyse geotechnical engineering. The physical significance of SMP criterion is most explicit than other strength criteria, its expression is nonlinear, and its Secondary development has important meaning. The viscoelasto-plastic rheological constitutive model with SMP strength criterion is developed according to the further developing platform in FLAC3Dwith VC++;and the SMP criterion is deduced to adapt to cohesive soil. At last, its accuracy and reliability are confirmed by a simple engineering calculation. The proposed mode can bring forward references for the secondary development of other rheological models and strength criteria.
