Given soil formation and the corresponding properties of soil in each layer. To consolidate the ground, a load is added at the top as shown or dewatering are being considered. (A) With the load only, what is the increase in stress at mid-layer of the bottom soil assuming a trapezoidal stress distribution of 1 horizontal to 2 vertical. (B) With dewatering by 2 m., what is the stress increase at the mid layer at the bottom of soil as water is lowered down? (C) How much must the water level be lowered to be more effective than the load added at the top?
