The particle beds analyzed in this paper consist of comparativly large spherical glass beads assemblies at low consolidations. At the condition that the degree of freedom of particle motion is not zero, various constants of particle bed change discontinuously with increasing normal pressure, and a gredient of constants to normal pressure decreases with increasing normal pressure. It is guessed that properties of the particle bed change from those of discontinuous body into those of continuous one. The fact indicates that assumption of Janssen or other equations used in structural design of storage vessel is inadequate for comparatively large particle assemblies at least.<BR>The behaviors of particle in a shear box are thought of as three processes for instance. In the first, the particl motions are completely free, and then each particle is able to both spin and move straight. In the second, the particle motions are constrained partly, and then each particle subjected to shear force is able to only spin or move straight. Straight motion may be constrained earlier than spinning motion on increasing normal pressure. In the third, the particle motion is constarained completely, and particle assemblies subjected to shear force glide on a particle surface.
