A soil profile (Clayey soil) is studied where the void ratio (e) is 1 and the specific gravity of solid particles (Gs) is 2.7. You are required to find out at what depth (meter) the effective stress is equal to pore water pressure. The water unit weight is 10 kN/m3. Below the second layer, there is a bedrock. Unit weight for the first layer is 16 kN/m3 and unit weight for the second layer is 18.5 kN/m3. Saturation of the first layer is 0.5 (S=0.5). The second layer saturation is 1 (S=1).
