The goal of this study is to propose a novel method for achieving similitude between small scale 1g models and prototypes for cohesionless soils. A new 1g model preparation method is proposed for cohesionless soils that achieves 1g model and prototype dilatant behavior equivalency. For this purpose a new dilatancy function is used that allows the calculation of dilatancy angle based on in-situ mean effective stress and relative density. The new equation requires the input of two empirical unit independent parameters that can be obtained by conducting a small number of triaxial or plane strain tests. The proposed method is used during model preparation for small scale retaining wall tests and the influence of controlled dilatancy on the geometries of failure planes during active and passive failure surfaces are monitored using particle image velocimetry. The results of these tests are presented and the efficiency of the proposed method is discussed in this paper.
