Phase2 Tutorials > Geogrid Reinforced Embankment (with slip)
In Tutorial 11, we performed a shear strength reduction (SSR) analysis for a sand embankment on top of a soft clay layer with a geogrid liner in between. We will now proceed with the same model and add the following features:
Allow slip between the geogrid liner and the soil layers.
Construct the model in two stages. The first stage simulates only the clay layer. The geogrid and the sand fill embankment are added in the second stage.
