Abstract:Medium-scale dynamic triaxial tests are carried out to investigate the
   residual deformation behaviors of simulated municipal solid waste(MSW).
   Based on revised Shen Zhu-jiang model, parameters for modeling residual
   deformation of MSW are derived. Given three typical failure criteria,
   the effect of stress levels on model parameters is studied, and a stress
   level index is fitted to model the residual deformation of MSW.As the
   MSW is a kind of strain-hardening material,no clear peak is shown on
   stress-strain curve. The MSW with the same consolidation ratio results
   in varied stress levels in the model if multiple failure criteria are
   considered. To eliminate the choice of failure criterion and make the
   model parameter derivation straightforward, the stress level is replaced
   by the consolidation stress ratio, which leads to a modified and
   simplified model to estimate residual deformation of MSW.The modified
   model is verified by using the test results and will be used
   conveniently regardless of different failure criteria
