52.2. Problem Description

An embankment of three equal layers is constructed over 4.5 days at 1.5 days per layer.

During the construction of each embankment layer, the clay layer undergoes consolidation. Each embankment layer is 0.6 m thick. Loading for each step consists only of the weight of the embankment and the clay layer's effective self-weight.

The material under the clay is impermeable, as are the contact regions between the clay and the embankment, and between each embankment layer.

The embankment is assumed to exhibit linear elastic behavior. The clay layer uses an elastoplastic Cam-clay material model.
