Biot's consolidation theory was used to serve as a frame working with the nonlinear elastic model or with elasto-plastic model in the program. Nonlinear elastic model includes Duncan-Zhang model, Gong Xiannan Ko consolidation model and the model proposed in chapter 2. Elasto-plastic model in the program includes Mohr-Coulomb model, Drucker-Prager model and the bounding surface model developed in chapter 3. The program can be used in cases of plane problem and axisymmtric problem.
