Large Strain Consolidation for Elasto-Plastic Soils
Large stain formulation for two phase medium i.e. soil skeleton and ground water, is studied in the paper. The updated Lagrange procedure is developed for the fully coupled consolidation process. The pseudo-visco-plastic iteration procedure is applied to solve the large strain elasto-plastic consolidation problems. The equations are developed in the finite element code. The numerical tests for elastic and elasto-plastic soil skeleton are performed. The obtained results for plain stains problem are reported and studied in details. As the engineering example, the consolidation of the mud layer below the earth dam is studied in the paper.
