1. From the results of soil borings made at a site in Boston, the soil profile shown below was developed. Compute the total stress, pore water pressure, and effective stress in the profile at 0', 4', 8', 10.5', 13', 28', and 43' depths and plot your results. Assume that the water pressure above the ground water table is zero. (Note: Use the following scales to draw your plots: Depth 1" = 10'; Stress: 1" = 1000 psf.) Ignore capillarity. Sand Y₁ = 125 pcf Sand Clay Y₁ = 115 pcf 8' 5' Yt = 125 pcf 30' 2. Repeat problem 1 without ignoring capillarity. Assume that the height of capillary rise is greater than 8 feet.
