MODEL MATERIAL CHOOSING IN CENTRIFUGE MODELING OF EMBANKMENT REINFORCED WITH GEOGRID

Whether the model test data can be extrapolated to the prototype scale and so give a sensible assessment of its behavior is based on the similarity between the model and corresponding prototype, so it is necessary to follow appropriate scaling laws in choosing model material. Because of the restriction on geometry, it is important to assess the relative effects of key parameters to replicate the essential features of the prototype. Model material including geogrid, plastic drain, foundation, embankment, sand cushion will be discussed in this paper in centrifuge modeling of embankment on soft clay reinforced with geogrid.
