A 2-m-thick clay layer with two different drainage conditions (case A and case B) is shown in Figure 4.31. A uniformly distributed load, q = 500 kPa, is applied at the ground surface. Calculate the primary consolidation settlement of the normally consolidated clay layer for the two cases. Which case has more settlement? Assume the following: For sand, γ_sat
= 18 kN/m³. For clay, γ_sat
= 19 kN/m³, C_c
= 0.27, C_v
= 3 × 10⁻⁶
m²/min, and k = 4.37 × 10⁻⁹
m/min.
