The Jaky's K0 equation is commonly used for the estimation of K0 in practice, which is given as a function of the internal friction angle of soils. As the friction angle is a state-dependent variable, uncertain aspect still exists regarding the value of to be adopted for the Jaky's K0 equation. In this study, the applicatio n of the Jaky's K0 equation for granular materials is investigated with focus on the effect of particle characteristics, which are related to strength, on K0 behavior. Particle shape and angularity of particles are considered for the investigation of K0 behavior. Experimental testing program is established to measure K0 under various mechanical and physical conditions of test materials. Sand particles and spherically shpaed glass beads with and without etched particle surfaces are employed into the experimental testing program.
