Question-1: Explain the difference between the active, at-rest, and passive earth pressure conditions. Active conditions is when there's a lateral force on the wall like windy will Passive condition is the resisting bud force to support the wall At rest conditions is when there's as active .. - Passive forces. lower bound Question -2: Which of the three earth pressure conditions should be used to design a rigid basement wall? Why? At vest conditions, because it's fixed from both sides and not a cantireves, but it's better to design it for active conditions be extent's more safe. ? Question - 3: Consider a 10-foot tall concrete retaining wall. The backfil behind the wall will be a granular soil with a dry unit weight of 16,5 kN/m' and an angle of friction =30. The wall will not have to retain water. Estimate the lateral force on the wall from the backfill: a) In an active pressure condition. At rest condition Ko = (1 - sino). b)
