Question
The provided image is a soil profile diagram for calculating the total primary consolidation settlement due to 150 KPa net foundation loading. Key points from the diagram include:

1. **Structure Description:**
   - The base of the loading area is a structure with dimensions 10 m x 10 m.
   - A net pressure (\( q_{\text{net}} = 150 \) KPa) is applied to this structure.
   - The groundwater table (G.W.T) is positioned below the base of the clay layers.

2. **Soil Layers:**

   - **Clay 1:**
     - Thickness: 8 m (2 m top unsaturated, 6 m saturated)
     - Dry unit weight (\( \gamma_{\text{dry}} \)): 19 KN/m\(^3\)
     - Saturated unit weight (\( \gamma_{\text{sat}} \)): 20 KN/m\(^3\)
     - Pre-consolidation pressure (\( P_c \)): 80 KPa
     - Initial void ratio (\( e_o \)): 0.8
     - Compression index (\( C_c \)): 0.15
     - Recompression index (\( C_r \)): 0.05

   - **Clay 2:**
     - Thickness: 6 m
     - Saturated unit weight (\( \gamma_{\text{sat}} \)): 20 KN/m\(^3\)
     - Pre-consolidation pressure (\( P_c \)): 200 KPa
     - Initial void ratio (\( e_o \)): 0.6
     - Compression index (\( C_c \)): 0.1
     - Recompression index (\( C_r \)): 0.03

3. **Underlying Layer:**
   - The layer beneath Clay 2 is described as incompressible.

The objective is to calculate the total primary consolidation settlement of the soil profile given these conditions.
