Finite element analysis of the unsupported excavations using the elastoplastic bounding surface model

Finite element analyses of unsupported excavations in saturated clay were performed using the elastoplastic bounding surface model. In this paper, the model and the finite element formulation are described and examples of model prediction and accuracy of the finite element formulation are given. The transient analysis of excavation problems is then carried out, and the results of the analysis are presented which demonstrate the effects of the consolidation process and permeability on the stability of the excavation.
