The soil profile at a site consists of 10 m of gravelly sand underlain by a soft clay layer. The water table lies 1 m below the ground level. The moist and saturated unit weights of the gravelly sand are 17.0 kN/m3 and 20.0 kN/m3, respectively. Due to some ongoing construction work, it is proposed to lower the water table to 3 m below the ground level. What will be the change in the effective stress on top of the soft clay layer?

Effective Stress in Soil Problem 1. The water table in a certain deposit of soil is at a depth of 2m below the ground surface. The soil consists of clay up to depth of 4m from the ground and below which lies sand. The clay soil is saturated even above the water table: Clay strata: ? = 30%,?? = 2.72 Sandy Strata: ? = 26%, ?? = 2.64 1. Compute the total pressure. 2. Compute the pore water pressure. 3.

A soil exists in an area where the ground surface is level and the groundwater table is 3 m below the surface. The saturated unit weight for the soil is 22 kN/m3, and the wet weight for the soil above the water table is 18 kN/m3. The lateral pressure is 0.5 times the vertical pressure. The vertical and lateral pressures represent principal stresses. Determine the value for the major and minor principal stresses at a depth of 10 m (determine values for both the total stress and effective stress condition), and the maximum shear stress that develops because of the effective principal stresses.
