Abstract

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.
