There is a growing community of researchers that uses the geotechnical centrifuge, as a research tool, to gain insight into the mechanistic behavior of geosynthetically reinforced earth retaining structures. In this paper the principles of stress-correct physical modeling are highlighted. Examples of several case histories are provided to show how researchers iri different countries of the world have used this modeling technique in their work. The preliminary results of an ongoing research project on geotextile reinforced cohesive soil slopes and embankments using geotechnical centrifuge are presented.
