Prepare a series of plots of total horizontal stress versus depth from the ground surface to a depth of 20 ft.

7’0 Prepare a series of plots of total horizontal stress (on) versus depth from the ground surfaceto a depth of 20 ft. Plot values of on that are representative of the lateral pressures onunyielding basement walls (at-rest condition), walls that move away from the backfill(active condition), and walls that are pushed into the soil (passive condition). Use Rankinetheory to predict the active and passive pressures. To cover the range in possible conditionsat different locations across the site, consider locations where the depth to the groundwatertable is 10 ft or 20 fl, and where the ground surface in the vicinity of the wall is level or has a slope of 5H:1V (see the sketches). Hence, you will need to plot cm vs. depth for atleast 12 cases: Depth to Surface slope; oundwater ft H: ——_ An-Roon ——_ LevelConditions GroundSurface 1 0Active 20 Conditions 10Passive 20Conditions 20
