Problem 5 You are to examine the retaining wall shown on Figure 2. Assume that the wall height (H) is equal to 12 feet, and the base width (B) is 7 feet. The wall will be approximately 200 feet long (into the page). The backfill material behind the wall is a poorly-graded sand with silt (ŚP-SM) that has an average total unit weight of 1 19 pounds per cubic foot (pcf) and an average water content of 12%. As indicated,...
