| Abstract: | The purpose of this work is to develop a general nonlinear analysis program for soil consolidation. Based on variational principle, the fundamental equations are put forward for consolidation analysis of elasto-plastic saturated soil. A general analysis program DIASS has been developed in terms of the theory given. The computational methods dealing with nonlinear elastic and elasto-visco-plastic constitutive model of soil are discussed. |
