Basic Principles in Soil Mechanicssilts (Fig. 1.1), while the latter is clayey soil (Fig. 1.2). The mechanical properties of granular soils are governed by the grain-to-grain contact as well as friction. Hence, the magnitude of contact force and the geometrical nature of grain packing play major roles. It should be recalled that the
