The soil profile presented in Figure Q3 shows a borehole at a site where the water level is at 4m below the ground surface, with fine sand saturated by capillary action. Take G₁ = 2.7, K₂ = 0.5. (a) Calculate the effective stress at the centre of the soft clay layer. (b) Plot the distributions of the effective stress with depth. (c) Calculate the horizontal total stress at 13m.

Very fine moist sand with Silt, with water
content = 7% and dearee of saturation = 45%
Find sand saturated by capillary action
Find sand with water content = 14%
Soft clay with water content = 30%
