Zone I of elastic equilibrium 2. Zones II of radial shear state 3. Zones III of Rankine passive state When load qu per unit area acting on the base of the footing of width B with a rough base is transmitted into the soil, the tendency of the soil located within zone I is to spread but this is counteracted by friction and adhesion between the soil and the base of the footing.
The standard penetration test is mostly utilized in-situ test. It is ideal for cohesionless soils as it can not be sampled smoothly. The test is conducted to find out the pertinent density as well as the angle of shearing resistance of cohesionless soils.
