The soil profile at a certain site is as follows:Depth (ft) g (lb/ft3) c′ (lb/ft2) f′ (degree) su (lb/ft2)0–12 119 1,00012–20 126 200 2020–32 129 0 32 The groundwater table is at a depth of 15 ft.Develop plots of pore water pressure, total vertical stress, effective total stress, and shearstrength on a horizontal plane versus depth. All four of these plots should be superimposed onthe same diagram with the parameters on the horizontal axis (increasing to the right) and depthon the vertical axis (increasing downward).Hint: Because the cohesion and friction angle suddenly change at the strata boundaries,the shear strength also may change suddenly at these depths.

4. Look at the profile in page 53 of your reader. Calculate the hydrostatic pore pressure at the interface between the clay layer and the sand layer. 5. Use Excel to create a plot of hydrostatic pore pressure in kPa (x-axis) vs. depth in meters (y-axis) for the profile associated with problem 4 (above). We shall assume that the soil above the water table is dry, so clearly, the porewater pressure at z  6.5m is zero. Graph: line only (no markers); y-axis in reverse order, starting with z = 0 and ending with z = 14m (top of the bedrock). Label both axes and add tick marks to them. Remember: use an “x-y scatter” graph type
