In order to clarify the effect of particle-crushing on the shear characteristics of granular materi-als, high-pressure triaxial compression tests were made on two kinds of sands and the change in surface area of the samples during shearing was examined. It was shown that the surface area S depends not only on stress but also on strain, and hence it was suggested that S may be a function of plastic work done W. It was also found that the ratio (dS/dW)_f of a specimen at failure, which was defined as a measure of particle-crushing property, is closely related with the dilatancy rate (dv/dε_1)_f and the maximum principal stress ratio (σ'_1/σ'_3)_f at failure. Thus a new method was established here to relate the particle-crushing property to the shear characteristics of granular materials under triaxial stresses.
