The backfill behind a retaining wall, located above the water table, consists of a sand of unit weight 19 kN/m³. The height of the wall is 8 m and the surface of the backfill is horizontal. Determine the total active thrust on the wall according to the Rankine theory if c'=0 and q'=38. If the wall is prevented from yielding, what is the approximate value of the thrust on the wall?
