Abstract
Principles of centrifuge modeling in geotechnical engineering have been appreciated since the 1930's and explained by many researchers. Currently more than a hundred geotechnical centrifuges are in operation in various countries. Centrifuge model tests have been used a simulation of soil and structure in realistic scale to reveal unknown behaviors or to verify analytical or numerical estimation, and a direct simulation of the prototype existing somewhere or to be built in a future. In the present article, outline of the similitude of geotechnical centrifuge modeling, and current research projects are described.
