In a site consisting of normally consolidated clean sands, the water table is at 3.05 m depth. The average unit weight of the sand above and below the water table is 17.53 kN/m³ and 19.65 kN/m³, respectively. At a 7.62 m depth, N₆₀ was reported as 26. Determine the following:

a. (N₁)₆₀ using Liao and Whitman’s (1986) equation for CN [Eq. (3.13)]

b. Dr using Skempton’s (1986) correlation [Eq. (3.28)]

c. Friction angle using Schmertmann’s (1975) correlation [Eq. (3.30)]

d. Modulus of elasticity using Kulhawy and Mayne’s (1990) correlation [Eq. (3.32)]

Eq. (3.13)

Eq. (3.28)

Eq. (3.30)

Eq. (3.32)
