FINITE ELEMENT ANALYSIS OF CONSOLIDATION PROBLEM IN SEVERAL TYPES OF COHESIVE SOILS USING THE BOUNDING SURFACE MODEL

Finite element analyses of consolidation problem in several types of saturated cohesive soils were performed using the elastoplastic bounding surface model. In this paper, the model and the finite element formulation were described and examples of model prediction and accuracy of the finite element formulation were given. The transient response of the saturated porous media is based on Biot’s theory of consolidation. Transient analysis of a two-dimensional consolidation problem involving a flexible strip footing on a clay layer of finite thickness is then carried out which demonstrate the effects of consolidation process and model parameters on the pore pressure response and ground movements under the strip footing
