PLASTIC ZONE DEVELOPMENT DURING EMBANKMENT CONSTRUCTION

Rapid stage construction of homogeneous and isotropic embankments is examined. The finite element model constructed assumes an undrained, linearly elastic-perfectly plastic behaviour of the soil. The Von-Mises criterion is used to identify when the shear strength is exceeded. The plastic range analysis is based on Yamada et al's formulation of the inversion of the Pradetl-Reuss stress-strain relationships. For every strain increment, corresponding to the loads of a new layer, the stress increments are computed and added to the existing stresses. The new stress level defines the new stiffness matrix to be used in the subsequent loading. Numerical examples are solved using this process, which was coded in the computer program FEMDAM, and the expansion of the plastic zone is presented. The boundaries of the plastic zone may also constitute boundaries for a possible slip surface.(a) /TRRL/
