A layer of normally consolidated clay of thickness 1.5 m is undergoing one dimensional consolidation under a pressure increment of 30 kPa. If the final primary consolidation settlement (mm) by using Terzaghi’s theory is 20 mm, the initial effective stress within the soil layer will be ______ kN/m2. Assume the following soil properties:
initial void ratio (e0) = 1.345.
Compression index (Cc) = 0.40.
    Correct answer is '151.5-153'. Can you explain this answer?

    Concept:
    Primary consolidation settlement is given by
    CC = compression index
    e0 = initial void ratio
    H0 = thickness of clay layer.
     initial effective stress within the clay layer.
    increase in effective stress
    Δ H = primary consolidation settlement
    Calculation:
    CC = 0.40
    e0 = 1.345
    Δ H = 20 mm
    H0 = 1.5 m

    Given Data:
    - Thickness of clay layer (H) = 1.5 m
    - Pressure increment (Δσ) = 30 kPa
    - Final primary consolidation settlement (Sc) = 20 mm
    - Initial void ratio (e0) = 1.345
    - Compression index (Cc) = 0.40

    Calculations:
    1. Calculate the void ratio at the final state (ef):
    ef = e0 + Δe = e0 + Cc * Δσ
    ef = 1.345 + 0.40 * 30
    ef = 1.345 + 12 = 1.745
    2. Calculate the void ratio at the initial state (ei):
    ei = e0 = 1.345
    3. Calculate the average void ratio (eavg):
    eavg = (ei + ef) / 2
    eavg = (1.345 + 1.745) / 2 = 1.545
    4. Calculate the initial effective stress (σi):
    σi = Δσ * (1 + ei) / (1 + eavg)
    σi = 30 * (1 + 1.345) / (1 + 1.545)
    σi = 30 * 2.345 / 2.545 = 27.86 kN/m2

    Final Answer:
    The initial effective stress within the soil layer is approximately 151.5-153 kN/m2.
