In geotechnical engineering, small-scale model tests are often used to study the behavior of foundation structures. As generally known, the model tests should be satisfied the mechanical similarity as well as the similarity of scales in consideration of the level of effective stress within the soil mass. In order to satisfy these conditions, the centrifuge testing technique (e.g. M. Mikasa et al 1969; P. J. Avgherinos et al 1969) and the hydraulic gradient method (e.g. A. Zelikson 1969) have been developed. In this paper, the experimental results of model tests on the friction pile in sand by using the hydraulic gradient similitude method are presented. Furthermore, the model test results are compared with the predictions by finit element method, in which nonlinear soil behavior is taken into account.
