Question
### Problem 16.7 Determine the magnitude and the location of the active thrust on the smooth vertical wall shown in Figure P16.7, assuming that the entire backfill is in the active state. #### Description of Figure P16.7 - **Diagram Overview**: The diagram shows a vertical retaining wall against two layers of soil. 1. **Layers of Soil**: - **Top Layer**: - Thickness: 4.0 m - Material: Sand - Unit Weight (γ): 16.5 kN/m³ - Angle of Internal Friction (φ'): 34° - **Bottom Layer**: - Thickness: 3.0 m - Material: Silty Sand - Unit Weight (γ): 16.5 kN/m³ - Angle of Internal Friction (φ'): 36° - **Wall Description**: The vertical wall surface is smooth, indicating minimal friction resistance against lateral movement. This figure helps in determining active earth pressure on the retaining wall by considering the properties of different soil layers and their respective heights.
