A retaining wall with a smooth vertical back retains silt backfill for a depth of 6m. The backfill has a horizontal surface having following properties c = 10kPa, = 20° and N y = 17k. Calculate the percentage decrement in the magnitude of thrust on the m wall when the wall is restrained against yielding to when the wall is free to yield (assume development of tension crack when wall yields). A 32.8% B 45.7% C 50.3% D 61.4%
