8 Strength Of Soils And Rocks

Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement. The results of a number of direct shear tests are shown in Fig. 8.9. The sand yields a shear stress-normal stress plot similar to that of the sliding block in Fig. 8.7 but the clay gives anFig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.

Coarse-grained soils - gravel and sand. The composition or texture of a soil is a critical factor in its stability. The more cohesive the soil particles the more the entire soil mass tends to stick together rather than crumble. However, it is important to remember the time element involved in cuts.Coarse-grained soils - gravel and sand. The composition or texture of a soil is a critical factor in its stability.
