It was assumed that the embankment backfill was the same soil from the active earth coefficient experiment in Practical Two. But the filling material is not a pure sand. Discuss what effect this will have on the horizontal pressures on the retaining wall. Answer according to question asked!!
a) As a geotechnical engineer, explain why construction of foundations and other loads (structures) leads to a compression of soil layers. b) During the construction of a retaining wall, it was noticed that the wall does not yield toward the backfill or away from the backfill. Explain this phenomenon. Sketch a diagram to explain your answer. c) Let us consider the retaining wall shown in Figure below.
