%X A generalized constitutive theory of the boundary surface of soft clay with plastic deformation is established, based on the characteristics of soft soil deformation and variation of pore pressure under reversal loading. The boundary surface model is capable of simulating plastic deformation under low stress level. The linear elastic unloading process is improved and becomes an elasto-plastic one. Through comparison of numerical simulation results with tri-axial test data, its reliability is verified.
