摘要：

The definition of interparticle friction–in Rowe's and Horne's terms–allows us to research effects of petrographic characteristics of sand grains on their mechanical properties in mass, independently of the effect of packing parameters. It is known that this interparticle friction depends on the mineral composition of particles and on the state of their surface chemistry. Quantitative characterization of grain shape allows us to point out the effect of angularity on interparticle friction, for which a physical interpretation is proposed. Some tests results show that Horne's theoretical prediction on maximum dilatancy rate is not verified for highly rounded calcareous particles, thus demonstrating that the sphericity of particles has an effect on the types of assembly strain. © 1979, Thomas Telford Ltd.
