A soil specimen has been recovered from a site where 2 m of water overlie 3 m of soil. The soil specimen is found to have a dry unit weight, ya= 15 kN/m' and specific gravity G = 2.6. 1. Calculate the total and effective vertical stress at a depth of 5 m below the surface of the water. Assume that the soil properties do not vary with depth. 2. During construction the water table is lowered so that it is now 2 m below the soil surface. Assuming the dry unit weight remains constant, calculate the effective stress 3 m below the soil surface (at the same depth as in 1) when the moisture content in the soil above the water table is 7%.
